... WSVGA 24-Bit Long-Reach Video Serdes with Bidirectional Side-Channel The ISL34340 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 bidirectionally over the same link during the video vertical retrace interval ...

... The various differently-named Ground pins are internally weakly connected. They must be tied together externally. The different names are provided to assist in minimizing the current loops involved in bypassing the associated supply VDD pins. In particular, for ESD testing, they should be considered a common connection. 6 ISL34340 SERIALIZER 2 I ...
