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 parts adhere to the
TIA/EIA-899 standard for M-LVDS and complement TIA/EIA-
644 LVDS devices with additional multipoint capabilities.
The ADN4691E/ADN4693E are Type 1 receivers with 25 mV of
hysteresis, so that slow-changing signals or loss of input does
not lead to output oscillations. The ADN4696E/ADN4697E are
Type 2 receivers exhibiting an offset threshold, guaranteeing the
output state when the bus is idle (bus-idle fail-safe) or the inputs are
open (open-circuit fail-safe).
The parts are available as half-duplex in an 8-lead SOIC package
(the ADN4691E/ADN4696E) or as full-duplex in a 14-lead
SOIC package (the ADN4693E/ADN4697E). A selection table
for the ADN469xE parts is shown in Table 1.
