DESCRIPTION
The SN65LVDM1676 and SN65LVDM1677
(integrated termination) are sixteen differential line
transmitters or receivers (tranceivers) that use
low-voltage differential signaling (LVDS) to achieve
signaling rates up to 200 Mbps per transceiver
configured as a receiver and up to 650 Mbps per
transceiver configured as a transmitter. These
products are similar to TIA/EIA-644 standard
compliant devices (SN65LVDS) counterparts except
that the output current of the drivers are doubled.
This modification provides a minimum differential
output voltage magnitude of 247 mV into a 50-Ω load
and allows double-terminated lines and half-duplex
operation. The receivers detect a voltage difference
of 100 mV with up to 1 V of ground potential
difference between a transmitter and receiver.
