Description

The ISL34341 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.
