GENERAL DESCRIPTION
The ADN4691E/ADN4693E/ADN4696E/ADN4697E are multipoint, low voltage differential signaling (M-LVDS) transceivers (driver and receiver pairs) that can operate at up to 200 Mbps (100 MHz). 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 devices adhere to the TIA/EIA-899 standard for M-LVDS and complement TIA/EIA- 644 LVDS devices with additional multipoint capabilities.
