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.
The price listed is the manufacturer's suggested retail price for quantities of 1K units. However, prices in today's market are fluid and may change without notice.
