The ADN4690E / ADN4692E / ADN4694E / ADN4695E aremultipoint, low voltage differential signaling (M-LVDS)transceivers (driver and receiver pairs) that can operate at upto 100 Mbps (50 MHz). Slew rate control is implemented on thedriver outputs. The receivers detect the bus state with a differentialinput of as little as 50 mV over a common-mode voltage range of−1 V to +3.4 V. ESD protection of up to ±15 kV is implementedon the bus pins. The parts adhere to the TIA/EIA-899 standard forM-LVDS and complement TIA/EIA-644 LVDS devices withadditional multipoint capabilities.The ADN4690E / ADN4692E are Type 1 receivers with 25 mV ofhysteresis, so that slow-changing signals or loss of input doesnot lead to output oscillations. The ADN4694E / ADN4695E areType 2 receivers exhibiting an offset threshold, guaranteeing theoutput state when the bus is idle (bus-idle fail-safe) or theinputs are open (open-circuit fail-safe).The parts are available as half-duplex in an 8-lead SOIC package(the ADN4690E / ADN4694E) or as full-duplex in a 14-leadSOIC package (the ADN4692E / ADN4695E).APPLICATIONS Backplane and cable multipoint data transmission Multipoint clock distribution Low power, high speed alternative to shorter RS-485 links Networking and wireless base station infrastructure
