Analog Devices Inc. ADN4680E Quad M-LVDS Transceivers are driver and receiver pairs that can operate at up to 125MHz or 250Mbps nonreturn to zero (NRZ). The driver and receiver of each transceiver are connected in a half-duplex configuration. This configuration enables each transceiver to be configured via independent enable pins for either sending or receiving data.
The ADI ADN4680E Quad M-LVDS Transceivers provide Electrostatic discharge (ESD) protection of up to ±15kV via the bus pins. The transceivers are optimized for low dynamic power consumption for use in high-density applications. The ADN4680E is designed to the TIA/EIA-899 standard for use in M-LVDS networks and complement TIA/EIA-644 LVDS devices with additional multipoint capabilities.
The receivers detect the bus state with a differential input of as little as ±50 mV over a common-mode voltage range of −1V to +3.4V. Each receiver is pin selectable as a Type 1 or Type 2 receiver independently. Type 1 receivers have 15 mV of hysteresis so that slow-changing signals or loss of input does not lead to output oscillations. Type 2 receivers exhibit an offset threshold, guaranteeing the output state when the inputs are open (open circuit fail-safe), the bus is idle (bus idle or terminated fail-safe), or when the inputs are hard short-circuited.
The ADN4680E is offered in a compact 48-lead, 7mm × 7mm LFCSP package and has an operating temperature range of −40°C to +105°C.
