16-Bit Long-Reach Video Automotive Grade SERDES

ISL76322

The ISL76322 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. The fully featured register
