16-Bit Long-Reach Video Automotive Grade SERDES
with Bi-directional Side-Channel
ISL76321
The ISL76321 is a serializer/deserializer of LVCMOS parallel
video data. The video data presented to the serializer on the
parallel LVCMOS bus is serialized into a high-speed differential
signal. This differential signal is converted back to parallel video
at the remote end by the deserializer. It also transports auxiliary
data bi-directionally over the same link during the video vertical
retrace interval. I²C bus mastering allows the placement of
external slave devices on the remote side of the link. An I²C
controller can be placed on either side of the link allowing bi-
directional I²C communication through the link to the external
devices on the other side. Both chips can be fully configured from
a single controller or independently by local controllers.
