VX5OVERVIEWThe VX5 is a professional vocal condenser microphone designed for a wide variety of live, studio and broadcast applications. With an ability to duplicate studio quality sound on stage, the VX5 is known for its smooth and accurate frequency response, resistance to feedback and ability to handle very high sound pressure levels without distortion.The VX5 is characterized with a tight and uniformly controlled supercardioid polar pattern which helps to isolate the vocals from the rest of the instruments on stage. With a wide frequency range of 40 Hz - 16.5 kHz, the VX5 has a very clean and natural sound with exceptional transient response. This mic requires 9 - 52 volts phantom power.Other features include a 14 mm gold vapor diaphragm, an acoustically ported steel mesh grill with multi-stage pop filter and a -10 dB pad and bass roll-off filter. The VX5 will handle sound pressure levels in excess of 140 dB (with pad and roll-off engaged) and will provide over 20 dB of ambient noise rejection on live stages. In addition to vocal applications, the VX5 is ideally suited to capture acoustic instruments such as guitar, woodwinds, brass, percussion toys, drum overheads, hi-hat and piano. It is a very versatile mic for home studio recording. The VX5 is well balanced, comfortable to hold, durable, and designed with very high standards and tight tolerances.The VX5 is manufactured with a precision die cast zinc alloy body, durable black E-coat finish and gold plated XLR connector.SUPPLIED ACCESSORIESMC1 - Heavy-duty nylon molded clip with brass insert P1 - Carrying pouchOPTIONAL ACCESSORIESWS357 - Optional high quality external foam windscreen for reducing wind, sibilance, and pop noise.SMT25 - Optional low profile shock mount system with nylon cable and thumbscrew for positioning.APS2 - Two-channel 48 V phantom power supply for condenser microphones. 110 V switchable to 240 V.

When your preliminary setup is completed, and your USB microphone is connected to your computer’s USB port (the microphone’s blue LED is illuminated), plug your headphones into the headphone jack on the bottom of the microphone. While talking into the microphone, you should hear yourself in the headphones. Adjust the volume up or down by rotating the the Up/ Down dial on the bottom of the microphone. Note: The Up/ Down dial only adjusts the volume of the mic’s headphone output; it does not adjust the microphone level.Selecting softwareYou have many choices in recording software. Audacity, available for free online at/, is a widely used software program that provides basic recording software. Setting your software levelsCorrect adjustment of microphone level is important for optimum performance. Ideally, the microphone level should be as high as possible without overloading the input of your computer. If you hear distortion, or if your recording program shows levels that are consistently overloaded (at peak levels), turn the microphone volume (or level) down, either through your control panel (or system preferences) settings, or through your recording software. If your recording program shows insufficient level, you can increase the microphone gain either from the control panel (or system preferences) settings or through your recording program.No further microphone level adjustments should be needed, as long as the acoustic input does not change significantly.Positioning your microphoneIt is important to position the microphone directly in line (on axis) with the person speaking/singing or instrument (or other sound source) to achieve the best frequency response of the microphone.For use in speaking/singing applications, the ideal placement for the microphone is directly in front of the person speaking/singing. The same placement is optimal when miking an instrument such as an acoustic guitar, drums or piano. Experiment with different mic placements to find the best sound for your particular setup.XLR operationFor live-sound applications, connect the XLRF connector of the included XLR cable to the XLRM output on the bottom of the microphone; connect the cable’s XLRM connector to a standard XLRF microphone input on your mixer. Turn the microphone’s ON/OFF switch to the “ON” position. Set the microphone’s level by following the instructions included with your mixer. Note: The ON/OFF switch does not affect the LED.Protecting your microphoneTake care to keep foreign particles from entering the windscreen. An accumulation of iron or steel filings on the diaphragm, and/or foreign material in the windscreen’s mesh surface, can degrade performance.Element: DynamicPolar Pattern: CardioidFrequency Response: 50 – 15,000 HzPower Requirements: USB Power (5V DC)Bit Depth: 16 bitSample Rate: 44.1 kHz/48 kHzControls: On/off switch; headphone volume controlWeight: 266 g (9.4 oz)Dimensions: 183.6 mm (7.23") long, 51.0 mm (2.01") maximum body diameterOutput Connector: USB-type/XLR-typeHeadphone Output Power: 10 mW @ 16 ohmsHeadphone Jack: 3.5 mm TRS (stereo)Accessories Included: Stand clamp for 5/8"-27 threaded stands, tripod desk stand, 2 m (6.6') mini USB cable, 3 m (9.8') XLRF-type to XLRM-type cableSystem Requirements: Macintosh: MAC OS X; USB 1.0 or 2.0; 64 MB RAM (minimum) Windows: XP/Vista/Windows 7; USB 1.0 or 2.0; 64 MB RAM (minimum)†In the interest of standards development, A.T.U.S. offers full details on its test methods to other industry professionals on request.Specifications are subject to change without notice.AT2005USB Specifications †R e s p o n s e i n d B LEGEND 200 Hz 1 kHz 5 kHz 8 kHz SCALE IS 5 DECIBELS PER DIVISION240˚180˚210˚270˚300˚330˚0˚150˚120˚90˚30˚60˚Frequency ResponsePolar PatternAudio-Technica U.S., Inc.1221 Commerce Drive, Stow, Ohio 44224 USA +1 (330) 686-2600 ©2012 Audio-Technica U.S., Inc.

MICRF500BLQ资料

General DescriptionThe MICRF500 is a single chip UHF transceiver designed forspread spectrum communication (FHSS) intended for ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands from 700MHz to 1100MHz with FSK data rates up to 128k baud.The transmitter consists of a PLL frequency synthesizer and a power amplifier. The frequency synthesizer consists of a voltage-controlled oscillator (VCO), a crystal oscillator, dual-modulus prescaler, programmable frequency dividers and a phase-detector. The loop filter is external for flexibility and can be a simple passive circuit. The VCO is a Colpitts oscillator which requires an external resonator and varactor.FSK modulation can be applied externally to the VCO. The synthesizer has two different N, M and A frequency dividers.FSK modulation can also be implemented by switching between these dividers (max. 2400bps). The lengths of the N and M and A registers are 12, 10 and 6 bits respectively. For all types of FSK modulation, data is entered at the DATAIXO pin (see application circuit). The output power of the power amplifier can be programmed to eight levels. A lock detect circuit detects when the PLL is in lock.In receive mode the PLL synthesizer generates the local oscillator (LO) signal. The N, M and A values that give the LO frequency are stored in the N0, M0 and A0 registers. The receiver is a zero intermediate frequency (IF) type in order to make channel filtering possible with low-power integrated low-pass filters. The receiver consists of a low-noise amplifier (LNA) that drives a quadrature mixer pair. The mixer outputs feed two identical signal channels in phase quadrature. Each channel includes a preamplifier, a third order Sallen-Key RC low pass filter that protects the following gyrator filter from strong adjacent channel signals and finally, a limiter. The main channel filter is a gyrator capacitor implementation of a seven-pole elliptic low pass filter. The elliptic filter minimizes the total capacitance required for a given selectivity and dynamic range. The cut-off frequency of the Sallen-Key RC filter can be programmed to four different frequencies: 10kHz,30kHz, 60kHz and 200kHz. An external resistor adjusts the cut-off frequency of the gyrator filter. The demodulator de-modulates the I and Q channel outputs and produces a digital data output. It detects the relative phase of the I and the Q channel signal. If the I channel signal lags the Q channel, the FSK tone frequency lies above the LO frequency (data ‘1’). If the I channel leads the Q channel, the FSK tone lies below the LO frequency (data ‘0’). The output of the receiver is available on the DATAIXO pin. A RSSI (Receive Signal StrengthIndicator) circuit indicates the received signal level.Micrel, Inc. • 1849 Fortune Drive • San Jose, CA 95131 • USA • tel + 1 (408) 944-0800 • fax + 1 (408) 944-0970 • A two pin serial interface is used to program the circuit.External components are necessary for RF input and output impedance matching and decoupling of power. Other exter-nal components are the VCO resonator circuit with varactor,crystal, feedback capacitors and components for FSK modu-lation with the VCO, loop filter, bias resistors for the power amplifier and gyrator filters. A T/R switch can be implemented with 2-pin diodes.

With Manchester code the bitrate is half the baudrate, but with 3B4B block code the bitrate is 3/4 of the baudrate.Note 5:Bitrate is the same as the baudrate.Note 6:Measured at 19.2k bauds and frequency deviation ±25kHz (external modulation), jitter of received data: < 45%.P O U T (d B m )I TOT (mA)Output Power vs. Current @ 25°CFunctional DiagramFigure 1.Transceiver Internal BlocksTypical ApplicationFigure 2 shows an example of a transceiver with modulationapplied to the VCO.

The dual-modulus prescaler divides the VCO-frequency by 64/65. This mode is controlled by the A-divider. There are two sets of M, N and A-frequency ing both sets in transmit mode, FSK can be implemented by switching between those two sets. The phase-detector is a frequency/phase detector with back slash pulses to mini-mize phase noise. The VCO, crystal oscillator, charge pump,lock detector and the loop filter will be described in detail below.Voltage Controlled Oscillator (VCO)C38Figure 3.VCOThe circuit schematic of the VCO with external components is shown in Figure 3. The VCO is basically a Colpitts oscilla-tor. The oscillator has an external resonator and varactor.The resonator consists of inductor L1 and the series connec-tion of capacitor C13, the internal capacitance and the capacitance of the varactor. The capacitance of the varactor (D1) decreases as the input voltage increases. The VCO frequency will therefore increase as the input voltage in-creases. The VCO has a positive gain (MHz/Volt). If neces-sary a parallel capacitor can be added next to D1 to bring the VCO tuning voltage to its middle range or VDD/2, which is measured at Pin 9 - CMPOUT.If the value of capacitor C13 becomes too small the amplitude of the VCO signal decreases, which leads to lower output power.The layout of the VCO is very critical. The external compo-nents should be placed as close to the input pin (Pin 6) as possible. The anode of D1 must be placed next to Pins 7 and 8 in the PCB layout. G round vias should be next to component pads.Crystal OscillatorThe crystal oscillator is the reference for the RF output frequency as well as for the LO frequency in the receiver. The crystal oscillator is a very critical block since very good phase and frequency stability is required. The schematic of the crystal oscillator with external components for 10MHz is shown in Figure 4. These components are optimized for acrystal with 15pF load capacitance.10MHzXOSCOUTFigure 4.Crystal OscillatorThe crystal oscillator is tuned by varying the trimming capaci-tor C20. The drift of the RF frequency is the same as the drift of crystal frequency when measured in ppm. The total differ-ence in ppm, ∆f(ppm), between the tuned RF frequency and the drifted frequency is given by:∆f(ppm) = S T × ∆T + n × ∆t where:•S T is the total temperature coefficient of the oscillator frequency (due to crystal and components) in ppm °C.•∆T is the change in temperature from room temperature, at which the crystal was tuned.•n is the ageing in ppm/year.•∆t is the time (in years) elapsed since the transceiver was last tuned.The demodulator will not be able to decode data when ∆f(Hz) = ∆f(ppm) × f RF is larger than the FSK frequency deviation. For small frequency deviations, the crystal should be pre-aged, and should have a small temperature coeffi-cient. The circuit has been tested with a 10MHz crystal, but other crystal frequencies can be used as well.Prestart of XCOThe start-up time of a crystal oscillator is typically some milliseconds. Therefore, to save current consumption, the MICRF500 circuit has been designed so that the XCO is turned on before any other circuit block. During start-up the XCO amplitude will eventually reach a sufficient level to trigger the M-counter. After counting two M-counter output pulses the rest of the circuit will be turned on. The current consumption during the prestart period is approximately 300µA.Lock DetectorThe MICRF500 circuit has a lock detector feature that indi-cates whether the PLL is in lock or not. A logic high on Pin 15(LOCKDET) means that the PLL is in lock.The phase detector output is converted into a voltage that is filtered by the external capacitor C23, connected to Pin 14,LDC. The resulting DC voltage is compared to a reference window set by bits Ref0 – Ref5. The reference window can be stepped up/down linearly between 0V, Ref0 – Ref5 = 1, and Ref0 – Ref5 = 0, which gives the highest value (DC voltage)of the reference window. The size of the window can either be equal to two (Ref6 = 1) reference steps or four reference steps (Ref6 = 0).The bit setting that corresponds to lock can vary, depending on temperature, loop filter and type of varactor. Therefore, the lock detect circuit needs to be calibrated regularly by a software routine that finds the correct bit setting, by running through all combinations of bits Ref0 – Ref5. Depending on the size of the reference window, there will be several bit combinations that show lock. For instance, with a large reference window, as much as five bit combinations can make the lock detector show lock. To have the maximum robustness to noise, the third of the bit settings should be chosen.Charge PumpThe charge pump can be programmed to four different modes with two currents, ±125µA and ±500µA. Bit 70 and 71 in the control word (cpmp1 and cpmp0) controls the operation. The four modes are:1.cpmp1=0Current is constant ±125µA. Used incpmp0=0applications where short PLL locktime is not important.2.cpmp1=0Current is constant ±500µA. Used incpmp0=1applications where a short PLL locktime is important, e.g., internal modula-tion. See “Modulation Inside PLL”section.3.cpmp1=1Current is ±500µA when PLL is out ofcpmp0=0lock and ±125µA when it is in lock.Controlled by LOCKDET (Pin 15). Locktime is halved.See “Modulation Outside PLL” section.4.cpmp1=1Same as above in Tx. In Rx the currentcpmp0=1is ±500µA. Used when using dual-loopfilters. See “Modulation Outside PLLDual-Loop Filters” section.Tuning of VCO and XCOThere are two circuit blocks that may need tuning, the VCO and the crystal oscillator.VCO TuningWhen the VCO voltage is not at its mid-point, a capacitor may be added in parallel with D1or by small increments changes in the L1 or C13 values.This is particularly important when using VCO modulation. The gain curve of the VCO (MHz/Volt) is not linear and the gain will therefore vary with loop voltage. This means that the FSK frequency deviation also varies with loop voltage. When using internal modulation, tuning the VCO can be omitted as long as the VCO gain is large enough to allow the PLL to handle variations in process parameters and tempera-ture without going out of lock.XCO TuningTune the trimming capacitor in the crystal oscillator to the precise desired transmit frequency. It is not possible to tune the crystal oscillator over a large frequency range. N, M and A values must therefore be chosen to give a RF frequency very close to the desired frequency. Because of the small tuning range the VCO will not go out of lock when tuning the crystal oscillator.FSK ModulationThe circuit has two sets of frequency dividers A0, N0, M0 and A1, N1, M1. The frequency dividers are programmed via the control word. A0, N0, M0 are to be programmed with the receive frequency and are used in receive mode. There are three ways of implementing FSK:•FSK modulation can be applied to the VCO. This way of implementing FSK modulation is ex-plained more in detail in the next section. Thevalues corresponding to the transmit frequencyshould be programmed in dividers A1, N1 andM1. Pin DATAIXO must be kept in tri-state fromthe time Tx-mode is entered until one startssending data.•FSK modulation by switching between the two sets of A, N and M dividers. A, N and M valuescorresponding to the receive frequency and bothtransmit frequencies have to be found. Intransmit the values corresponding to data ‘0’should be programmed in dividers A0, N0 andM0, and the values corresponding to data ‘1’should be programmed in dividers A1, N1 andM1.•FSK modulation by adding/subtracting 1 todivider A1. The frequency deviation will be equalto the comparison frequency. The valuescorresponding to the transmit frequency shouldbe programmed in dividers A1, N1 and M1.For all types of FSK modulation, data is entered at the DATAIXO pin.Loop FilterThe design of the loop filter is of great importance for optimizing parameters like modulation rate, PLL lock time, bandwidth and phase noise. Low bitrates will allow modula-tion inside the PLL, which means the loop will lock on different frequency for 1s and 0s. This can be implemented by switch-ing the internal dividers (M, N and A).Higher modulation rates (above 2400bps) imply implementa-tion of modulation outside the PLL. This can be implemented by applying the modulation directly to the VCO.Loop filter values can be found using an appropriate software program.Modulation Inside PLLA fast PLL requires a loop filter with relatively high bandwidth. If a second order loop filter is chosen, it may not give adequate attenuation of the comparison frequency. There-fore in the following example a third order loop filter is chosen. Example 1:Radio frequency f RF868MHzComparison frequency f C100kHzLoop bandwidth BW 3.8kHzVCO gain K o30MHz/VPhase comparator gain K d500µA/radPhase margin j62°Breakthrough suppression A20dBThe component values will be:OUTINFigure 5.Third Order Loop FilterWith this loop filter, internal modulation up to 2400bps ispossible. The PLL lock time from power-down to Rx will beapproximately 1ms.Modulation Outside PLL (Closed Loop)When modulation is applied outside the PLL, it means that thePLL should not track the changes in the loop due to themodulation signal. A loop filter with relatively low bandwidthis therefore necessary. The exact bandwidth will depend onthe actual modulation rate. Because the loop bandwidth willbe significantly lower than the comparison frequency, asecond order loop filter will normally give adequate attenua-tion of the comparison frequency. If not, a third order loop filtermay give the extra attenuation needed.Example 2:Radio frequency f RF868MHzComparison frequency f C140kHzLoop bandwidth BW900HzVCO gain K o30MHz/VPhase comparator gain K d125µA/radPhase margin j61°The component values will be:OUTINCmpRFigure 6.Second Order Loop FilterData rates above approximately 19200baud (includingManchester coding) can be used with this loop filter withoutsignificant tracking of the modulating signal. PLL lock time willbe approximately 4ms.If a faster PLL lock time is wanted, the charge pump can bemade to deliver a current of 500µA per unit phase error, whilean open drain NMOS on chip (Pin 10, CmpR) switches in asecond damping resistor (R10) to ground as shown in Figure6. Once locked on the correct frequency, the PLL automati-cally returns to standard low noise operation (charge pumpcurrent: 125µA/rad). If correct settings have been made in thecontrol word (cpmp1=1, cpmp0=0), the fast locking featureis activated and will reduce PLL lock time by a factor of twowithout affecting the phase margin in the loop.Components C17, C18 C19, R11, R12 and R13 (see applica-tion circuit) are necessary if FSK modulation is applied to theVCO. Data entered at the DATAIXO pin will then be fedthrough the Mod pin (Pin 11) which is a current output. The pinsources a current of 50µA when Logic 1 is entered at theDATAIXO and drains the current for Logic 0. The capacitanceof C17 will set the order of filtering of the baseband signal. Alarge capacitance will give a slow ramp-up and therefore ahigh order of filtering of the baseband signal, while a smallcapacitance gives a fast ramp-up, which in turn also gives abroader frequency spectrum. Resistors R11 and R12 set thefrequency deviation. If C18 is large compared to C17, thefrequency deviation will be large. R13 should be large toavoid influencing the loop filter. Pin DATAIXO must be keptin tri-state from the time Tx-mode is entered until one startssending data.Modulation Outside PLL, Dual-Loop FiltersModulation outside the PLL requires a loop filter with arelatively low bandwidth compared to the modulation rate.This results in a relatively long loop lock time. In applicationswhere modulation is applied to the VCO, but at the same timea short start-up time from power down to receive mode isneeded, dual-loop filters can be implemented. Figure 7shows how to implement dual-loop filters.towards_VCOFigure 7.Dual-Loop FiltersThe loop filter used in transmit mode is made up of C15, C16,R9 and R10. The fast lock feature is also included (internalNMOS controlled by FLC, Fast Lock Control). This filter isautomatically switched in/out by an internal NMOS at Pin 4,QchOut, which is controlled by DFC (Dual Filter Control). BitsOutS2, OutS1, OutS0 must be set to 110. When QchOut isused to switch the Tx loop filter to ground, neither QchOut norIchOut can be used as test pins to look at the different receiversignals. The receive mode loop filter comprises C115, C116,R109, R101 and C101.Modulation Outside PLL (Open Loop)In this mode the charge pump output is tri-stated. The loop isopen and will therefore not track the modulation. This meansthat the loop filter can have a relatively high bandwidth, whichgive short switching times. However, the loop voltage willdecrease with time due to current leakage. The transmit timewill therefore be limited and is dependent on the bandwidth ofthe loop filter. High bandwidth gives low capacitor values andthe loop voltage will decrease faster, which gives a shortertransmit time.The loop is closed until the PLL is locked on the desiredfrequency and the power amplifier is turned on. The loopimmediately opens when the modulation starts. The loop willnot track the modulation, but the modulation still needs to beDC free due to the AC coupling in the modulation network.TransmitPower Amplifier (PA)The power amplifier is biased in class AB. The last stage has an open collector, and an external load inductor (L2) is therefore necessary. The DC current in the amplifier is adjusted with an external bias resistor (R14). A good starting point when designing the PA is a 1.5kΩ bias resistor which gives a bias current of approximately 50µA. This will give a bias current in the last stage of about 15mA.The impedance matching circuit will depend on the type of antenna used, but should be designed for maximum output power. For maximum output power the load seen by the PA must be resistive and should be about 100Ω. The output power is programmable in eight steps, with approximately 3dB between each step. This is controlled by bits Pa2 - Pa0. To prevent spurious components from being transmitted the PA should be switched on/off slowly, by allowing the bias current to ramp up/down at a rate determined by the external capacitor C25 connected to Pin 24. The ramp up/down current is typically 1.1µA, which makes the on/off rate for a 3.0V power supply 2.6µs/pF. Turning the PA on/off affects the PLL. Therefore the on/off rate must be adjusted to the PLL bandwidth.PA BufferA buffer amplifier is connected between the VCO and the PA to ensure that the input signal of the PA has sufficient amplitude to achieve the desired output power. This buffer can be bypassed by setting the bit Gc to 0.ReceiveFront End (LNA and Mixers)A low noise amplifier in RF receivers is used to boost the incoming signal prior to the frequency conversion process. This is important in order to prevent mixer noise from domi-nating the overall front end noise performance. The LNA is a two-stage amplifier and has a nominal gain of 23dB at 900MHz. The LNA has a dc feedback loop, which provides bias for the LNA. The external capacitor C26 decouples and stabilizes the overall dc feedback loop, which has a large low frequency loop gain. Figure 8 shows the input impedance of the LNA. Input matching is very important to get high receive sensitivity.The LNA can be bypassed by setting bit ByLNA to ‘1’. This is useful for very strong signal levels.The RSSI signal can be used to drive a microcontroller in a way when a strong RF income signal is present the LNA can be bypassed. This will increase the dynamic range by ap-proximately 25dB.The mixers have a gain of about 12dB at 900MHz. The differential outputs of the mixers are available at Pins 34, 35 and at Pins 38, 39. The output impedance of each mixer is about 15kΩ.Figure 8.Input ImpedanceSallen-Key Filter and PreamplifierEach channel includes a preamplifier and a prefilter, which is a three-pole elliptic Sallen-Key low pass filter with 20dB stopband attenuation. It protects the following gyrator filter from strong adjacent channel signals. The preamplifier has a gain of 20dB when bit Gc=0 and 30dB when bit Gc=1. The output voltage swing is about 200mV PP for the 30dB gain setting and 1V PP for the 20dB gain setting.The third order Sallen-Key low pass filter is programmable to four different cut-off frequencies according to the table below: Fc1Fc0Cut-Off Frequency Recommended(kHz)Channel Spacing 0010 ±2.525kHz0130 ±7.5100kHz1060 ±15200kHz11200 ±50700kHzFor the 10kHz cut-off frequency the first pole must be gener-ated externally by connecting a 820pF capacitor between the outputs of each mixer. For the 30kHz cut-off frequency a 68pF capacitor is needed between the outputs.As the cut-off frequency of the gyrator filter can be set by varying an external resistor, the optimum channel spacing will depend on the cut-off frequencies of the Sallen-Key filter. The table above shows the recommended channel spacing depending on the different bit settings.Gyrator FilterThe main channel filter is a gyrator capacitor implementation of a seven-pole elliptic low pass filter. The elliptic filter minimizes the total capacitance required for a given selectiv-ity and dynamic range. An external resistor can adjust the cut-off frequency of the gyrator filter. The following table shows how the cut-off frequency varies with bias resistor:。

MIC5209
500mA Low-Noise LDO Regulator
General Description
The MIC5209 is an efficient linear voltage regulator with very low dropout voltage, typically 10mV at light loads and less than 500mV at full load, with better than 1% output voltage accuracy. Designed especially for hand-held, battery-powered devices, the MIC5209 features low ground current to help prolong battery life. An enable/shutdown pin on SO-8 and TO-263-5 versions can further improve battery life with near-zero shutdown current. Key features include reversed-battery protection, current limiting, overtemperature shutdown, ultra-low-noise capability (SO-8 and TO-263-5 versions), and availability in thermally efficient packaging. The MIC5209 is available in adjustable or fixed output voltages.
