GENERAL DESCRIPTION

The ADN4690E/ADN4692E/ADN4694E/ADN4695E are multipoint, low voltage differential signaling (M-LVDS) transceivers (driver and receiver pairs) that can operate at up to 100 Mbps (50 MHz). Slew rate control is implemented on the driver outputs. The receivers detect the bus state with a differential input 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 implemented on the bus pins. The parts adhere to the TIA/EIA-899 standard for M-LVDS and complement TIA/EIA-644 LVDS devices with additional multipoint capabilities.
