OPA357中文资料

proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes couldDIFFERENTIAL PHASEFigure 3. Multiburst (CCIR 18) Test Pattern (PAL) Figure 4. Multipulse Test Pattern (PAL)Figure 5. CCIR 17 Test Pattern (PAL)Gain errors most commonly appear as attenuation or peaking of the chrominance information. This shows up in the picture as incorrect color saturation. Delay distortion will cause color smearing or bleeding, particularly at the edges of objects in the picture. It may also cause poor reproduction of sharp luminence transitions.All waveforms in Figure 3 through Figure 5 were taken using the sag correction feature of OPA360. Figure 3 through Figure 5 show that the OPA360 causes no visible distortion or change in gain throughout the entire video frequency range.INTERNAL LEVEL SHIFTMany common video DACs embedded in digital media processors like TI’s TMS320DM270 and the new OMAP2420 processors operate on a single supply (no negative supply). Typically, the lowest point of the sync pulse output by these Video DACs corresponds to 0V. With a 0V input, the output of common single-supply op amps saturates at a voltage > 0V. This effect would clip the tip of the sync pulse and therefore degrade the video signal integity. The OPA360 employs an internal level shift circuit to avoid clipping. The input signal is typically shifted byFigure 6. Internal Level Shifter, Shifts Input Signal by Approximately 60mV to Prevent SyncTip ClippingThe level shift function is particularly useful when the output of the OPA360 is DC-coupled to the video load. However, it is also helpful when sag correction is employed. The offset helps to shift the video signal closer to the positive rail, so that with even a small 33µF coupling capacitor, the output is well outside the saturation limits of the OPA360. Figure 7 shows the output swing of the OPA360, operated on 3.0V supplies, with a 22µF sag correction capacitor and a 33µF output coupling capacitor. The test signal is a 50Hz signal constructed to generate a 1/2 black, 1/2 white screen. This video pattern is one of the most difficult patterns to display because it is the worst case signal regarding signal swing. A worst case signal such as this is highly unlikely in normal operation. Any other signal has a lower swing range. Note in Figure 7 that neither the white nor the black portion of the video signal is clipped.Figure 7. Output Swing with 33m F on 3V Supply OUTPUT SWING TO GND (SYNC PULSE)Figure 8 shows the true output swing capability of the OPA360 by taking the tip of the input sync pulse to a slightly negative voltage. Even when the output sync tip is at 8mV, the output shows no clipping of the sync pulse.Figure 8. Input Sync Tip at −30mV (Output ShowsNo Sign of Clipping)Figure 10. Standard Video Circuit with 220m F Capacitor (top trace) vs OPA360 with 22m F and47m F CapacitorsA field tilt equivalent to that achieved using the standard 220µF coupling capacitor can be achieved with a 22µF/67µF combination − see Figure 11. These capacitor values are optimized—sag correction capacitors larger than 22µF do not provide significant improvement. Smaller sag correction capacitors will lead to higher tilt.Figure 11. 220m F Standard Video Circuit (top trace) vs OPA360 with 22m F/67m FFigure 12. Output Swing with 47m F on 3V Supply Figure 13.

光耦357t参数

光耦357t参数引言光电耦合器(Optocoupler),也叫做光耦(Optoisolator),是一种将电信号和光信号进行隔离和传输的器件。

光耦利用光电转换效应实现输入信号与输出信号之间的电气隔离。

光耦357t是一种常用的光电耦合器,本文将详细介绍光耦357t的参数及其相关信息。

LF, HF, UHF都分别代表什么

LF, HF, UHF都分别代表什么

LF, HF, UHF都分别代表什么?和我们听的收音机道理一样,射频标签和阅读器也要调制到相同的频率才能工作。

LF,HF,UHF 就对应著不同频率的射频。

LF代表低频射频,在125KHz左右,HF代表高频射频,在13.56MHz左右,UHF代表超高频射频,在860至960MHz范围之内。

对一个RFID系统来说,它的频段概念是指读写器通过天线发送、接收并识读的标签信号频率范围。

从应用概念来说,射频标签的工作频率也就是射频识别系统的工作频率,直接决定系统应用的各方面特性。

在RFID系统中,系统工作就像我们平时收听调频广播一样,射频标签和读写器也要调制到相同的频率才能工作。

射频标签的工作频率不仅决定着射频识别系统工作原理(电感耦合还是电磁耦合)、识别距离,还决定着射频标签及读写器实现的难易程度和设备成本。

RFID应用占据的频段或频点在国际上有公认的划分,即位于ISM波段。

典型的工作频率有:125kHz、133kHz、13.56MHz、27.12MHz、433MHz、902MHz~928MHz、2.45GHz、5.8GHz等。

按照工作频率的不同,RFID标签可以分为低频(LF)、高频(HF)、超高频(UHF)和微波等不同种类。

不同频段的RFID工作原理不同,LF和HF频段RFID电子标签一般采用电磁耦合原理,而UHF及微波频段的RFID一般采用电磁发射原理。

目前国际上广泛采用的频率分布于4种波段,低频(125KHz)、高频(13.54MHz)、超高频(850MHz~910MFz)和微波(2.45GHz)。

每一种频率都有它的特点,被用在不同的领域,因此要正确使用就要先选择合适的频率。

低频段射频标签,简称为低频标签,其工作频率范围为30kHz~300kHz。

典型工作频率有125KHz 和133KHz。

低频标签一般为无源标签,其工作能量通过电感耦合方式从阅读器耦合线圈的辐射近场中获得。

低频标签与阅读器之间传送数据时,低频标签需位于阅读器天线辐射的近场区内。

安捷伦 HP 3577A 高性能组延迟测量仪说明书

Hig h-Pe rformance Group Delay Measurements The HP 3577 A measures group d\:lay directly by dividing the mea­sured phase changes across a selected frequency aperture by the aper­ture value. The frequency aperture can be set from 0.5% to I 6% of span with annotation directly in Hertz, thus allowing the user to cha nge span and still retain the same effective smoothing. Sophisticated measurements of both magnitude and phase distor­tion in communication systems can be made. Cables and transmission lines can be tested for maximally flat de­lay with a resolution of up to I psec.vector Noise AveragingNoise reduction in the HP 3577A is accomplished by Vector Noise Averaging and/or selectable Resolution Bandwidth fi l ters. With the proper use of these two noise reduction methods, greater than 130 dB dynamic range can typically be achieved.Built-in Error CorrectionThree-term Vector Error Correction in the HP 3577 A is used to remove the effects of directivity, frequency response, and source mis­match from one-port measurements. Similarly, vector normalization enhances the accuracy of two-port measurements at the push of a button. These powerful accuracy enhancement routines can be used to cancel the repeatable error introduced by cable and test fixtures. M oreover, the HP 3577 A can be easily upgraded to an HP 3577S Network Analyzer System with full twelve-term Vector Error Cor­rection, as the need for uncompromising measurement accuracy aris es.HP-18 ProgrammabilityThe HP 3577A is fully programmable over the Hewlett-Packard Interface Bus. Simple programming codes minimize the time it takes to develop control software for automatic measurements. Quickly ac­cess a single point or an entire 40 I-point trace in either fast binary or ASCII modes. Customize the built-in vector display via the HP-IB to draw test limit lines, operator instructions or connection diagrams.HP 3577 A Network AnalyzerA bb reviated SpecificationsSourceFrequencyRange: 5 Hz to 200 MHz.Resolution: 0.00 I Hz.Stability: ±SXJ0-8/day, 0 to 55°C.AmplitudeRange:+ 15 dBm to -49 dBm ( l.26Vrms to 793µ Vrms: 2dBV to -62 dBV) into a son load.Resolution: 0.1 dB.Accuracy: ± I dB at+ 15 dbm and I 00 kHz.

General Description
These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar transistors (BI-FET™ Technology). These amplifiers feature low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.
Features
Advantages n Replace expensive hybrid and module FET op amps n Rugged JFETs allow blow-out free handling compared
with MOSFET input devices n Excellent for low noise applications using either high or
