Observe precautions for handling.Notes:1.Frequency aging is the change in f C with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture, decreasing in subse-quent years.2.The center frequency, f C , is measured at the minimum insertion loss point, IL MIN , with the resonator in the 50Ω test system (VSWR ≤ 1.2:1). The shunt inductance, L TEST , is tuned for parallel resonance with C O at f C . Typically, f OS-CILLATOR or f TRANSMITTER is approximately equal to the resonator f C .3.One or more of the following United States patents apply: 4,454,488 and 4,616,197.4.Typically, equipment utilizing this device requires emissions testing and govern-ment approval, which is the responsibility of the equipment manufacturer.5.Unless noted otherwise, case temperature T C =+25°C±2°C.6.The design, manufacturing process, and specifications of this device are subject to change without notice.7.Derived mathematically from one or more of the following directly measured parameters: f C , IL, 3dB bandwidth, f C versus T C , and C O .8.Turnover temperature, T O , is the temperature of maximum (or turnover) fre-quency, f O . The nominal frequency at any case temperature, T C , may be calcu-lated from: f =f O [1-FTC (T O -T C )2]. Typically oscillator T O is approximately equal to the specified resonator T O .9.This equivalent RLC model approximates resonator performance near the reso-nant frequency and is provided for reference only. The capacitance C O is the static (nonmotional) capacitance between the two terminals measured at low frequency (10MHz) with a capacitance meter. The measurement includes para-sitic capacitance with "NC” pads unconnected. Case parasitic capacitance is approximately 0.05pF.

DESCRIPTIONAPPLICATIONS■Industrial Control, Utility Meters Building Automation, Instrumentation, Point of Sale The SP3070-3078E differential line transceivers are suitable for bidirectional communication on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA Standards. Each device consists of a differential driver and differential receiver. All devices operate from a 3.3V power supply.High receiver input impedance allows a large number of transceivers to share a common data bus while maintaining signal margin and without excessive loading or use of expensive repeaters. The high impedance driver output is maintained over the entire common-mode voltage range from -7 to +12V. Receivers will failsafe to logic 1 output when inputs are open,shorted or terminated. Drivers include built-in short-circuit protection and a thermal-overload shutdown to protect against excessive power dissipation from bus contention or cable faults.All RS485 inputs are ESD protected up to ±15kV (Air-Gap and Human Body Model) and up to ±8kV Contact discharge (IEC 1000-4-2).DEVICE ARCHITECTURE AND BLOCK DIAGRAMSCCZZCC 14 Pin Full Duplex:SP3070E, 250kbps slew limited SP3073E, 500kbps slew limited SP3076E, 16Mbps8 Pin Full Duplex:SP3071E, 250kbps slew limited SP3074E, 500kbps slew limited SP3077E, 16Mbps8 Pin Half Duplex:SP3072E, 250kbps slew limited SP3075E, 500kbps slew limited SP3078E, 16MbpsDevices are available in three industry standard architectures and footprints.

These devices feature fail-safe circuitry, which guar-antees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmis-sion line with all drivers disabled. The SP3070E, SP3072E, SP3073E, SP3075E, SP3076E and SP3078E also feature a hotswap capability allowing live insertion with-out error data transfer. The SP3070E, SP3071E and SP3072E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The SP3073E, SP3074E and SP3075E also offer slew -rate limits allowing transmit speeds up to 500kbps. The SP3076E, SP3077E, SP3078E driver slew rates are not limited, making transmit speeds up to 16Mbps possible.The SP3072E, SP3075E and SP3078E are half-duplex transceivers, while the SP3070E, SP3071E, SP3073E, SP3074E, SP3076E, and SP3077E are full duplex transceivers. All devices operate from a single 3.3V supply. Drivers are output short-circuit current limited. Thermal-shutdown circuitry protects drivers against excessive power dissipation. When activated, the thermal-shutdown circuitry places the driver outputs into a high-imped-ance state.RECEIVER INPUT FILTERINGSP3070-SP3075 receivers incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differ-ential signals that have very slow rise and fall times. Receiver propagation delay increases by 25% due to this filtering.FAIL SAFEThe SP3070 family guarantees a logic-high receiver output when the receiver inputs are shorted, open, or when they are connected to a terminated transmission line with all drivers disabled. If A - B is less than or equal to -200mV, RO is logic low. In the case of a terminated bus with all transmitters disabled the receiver's differential input voltage is pulled to 0V by the termination. With the receiver thresholds of the SP3070E family, this results in a logic high with a 50mV minimum noise margin. In compliance with the EIA/TIA-485 standard, the SP3070E family has a 50mV -200mV threshold.HOT-SWAP CAPABILITYWhen circuit boards are inserted into a hot backplane, differential disturbances to the data bus can lead to data errors. Upon initial circuit board insertion, the data communica-tion processor undergoes its own power-up sequence. During this period, the processor's logic-output drivers are high impedance and are unable to drive the DE and RE inputs of these devices to a defined logic level. Leak-age currents up to 10µA from the high-imped-ance state of the processor's logic drivers could cause standard CMOS enable inputs of a transceiver to drift to an incorrect logic level. Additionally, parasitic circuit board capaci-tance could cause coupling of VCC or GND to the enable inputs. Without the hot-swap capa-bility, these factors could improperly enable the transceiver's driver or receiver.When VCC rises, an internal pulldown circuit holds DE low and RE high for approximately 10 microseconds. After the initial power-up sequence, the pulldown circuit becomes trans-parent, resetting the hot-swap tolerable input. 15KV ESD PROTECTIONAs with all Sipex devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges en-countered during handling and assembly. The driver output and receiver inputs of the SP3070E family of devices have extra protec-tion against static electricity. Sipex's engi-neering team have developed state of the art structures to protect these pins against ESD of 15kV without damage. The ESD structures withstand high ESD in all states: normal op-eration, shutdown, and powered down. After an ESD event, the SP3070E - SP3078E keep working without latchup or damage.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the SP3070E - SP3078E are characterized for protection to the following limits:■±15kV using the Human Body Model ■±8kV using the Contact Discharge method specified in IEC 1000-4-2■±15kV AirgapESD TEST CONDITIONSESD performance depends on a variety of conditions. Contact Sipex for a reliability report that documents test setup, method-ology and results.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equip-ment. However, it does not specifically refer to integrated circuits. The SP3070E family of devices helps you design equipment to meet IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to EC 1000-4-2 is generally lower than that measured using the human body model.The air-gap test involves approaching the device with a charged probe. The contact-discharge method connects the probe to the device before the probe is energized.MACHINE MODELThe machine model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. The objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly.256 TRANSCEIVERS ON THE BUSThe standard RS-485 receiver input imped-ance is 12kΩ (1 unit load), and the standard driver can drive up to 32 unit loads. The SP3070E family of transceivers has a 1/8-unit load receiver input impedance (96Ω), allowing up to 256 transceivers to be con-nected in parallel on one communication line. Any combination of these devices as well as other RS-485 transceivers with a total of 32 unit loads or fewer can be con-nected to the line.REDUCED EMI AND REFLECTIONS The SP3070E, SP3071E and SP3072E fea-ture reduced slew-rate drivers that minimize EMI and reduce reflections caused by im-properly terminated cables, allowing error-free data transmission up to 250kbps. The SP3073, SP3074 and SP3075 offer higher driver output slew-rate limits, allowing trans-mit speeds up to 500kbps.LOW POWER SHUTDOWN MODELow-power shutdown mode is initiated by bringing both RE high and DE low. In shut-down, the devices typically draw only 50nA of supply current.RE and DE can be driven simultaneously; the parts are guaranteed not to enter shut-50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.Enable times tZHand tZLassume the part was not in a low-power shutdown state. Enable times tZH(SHDN)and tZL(SHDN)assume the parts were shut down. It takes drivers and receivers longer to become enabled from low-power shutdown mode tZH(SHDN) and tZL(SHDN)than from driver/receiver-dis-able mode (tZH, tZL)。

Itprovides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 315MHz. The RO3073 is designed specifically for wireless remote controls and security transmitters, typically for automotive-keyless-entry, operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.Absolute Maximum Ratings RatingValueUnitsCW RF Power Dissipation (See Typical Test Circuit)+0dBm DC Voltage Between Any Two Pins (Observe ESD Precautions)±30VDC Case Temperature-40 to +85°C Soldering Temperature (10 seconds/5 cycles Max)260°C315.0 MHz SAW ResonatorRO3073CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.Notes:1.Frequency aging is the change in f C with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.2.The center frequency, f C , is measured at the minimum insertion loss point, IL MIN , with the resonator in the 50Ω test system (VSWR ≤ 1.2:1). The shunt inductance, L TEST , is tuned for parallel resonance with C O at f C . Typically, f OSCILLATOR or f TRANSMITTER is less than the resonator f C .3.One or more of the following United States patents apply: 4,454,488 and 4,616,197 and others pending.4.Typically, equipment designs utilizing this device require emissions testing and government approval, which is the responsibility of the equipment manufacturer.5.Unless noted otherwise, case temperature T C =+25°C±2°C.6.The design, manufacturing process, and specifications of this device aresubject to change without notice.7.Derived mathematically from one or more of the following directly measured parameters: f C , IL, 3dB bandwidth, f C versus T C , and C O .8.Turnover temperature, T O , is the temperature of maximum (or turnover) frequency, f O . The nominal frequency at any case temperature, T C , may be calculated from: f =f O [1-FTC (T O -T C )2]. Typically, oscillator T O is 20°C less than the specified resonator T O .9.This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C O is the static (nonmotional) capacitance between pin1 and pin 2 measured at low frequency (10MHz) with a capacitance meter. The measurement includes case parasitic capacitance with a floating case. For usualgrounded case applications (with ground connected to either pin 1 or pin 2 and to the case), add approximately 0.25pF to C O .PbElectrical ConnectionsThis one-port, two-terminal SAW resonator is bidirectional. The terminals are interchangeable with the exception of circuit board layout.
