General Description
The MAX9217 digital video parallel-to-serial converter serializes 27 bits of parallel data into a serial data stream. Eighteen bits of video data and 9 bits of control data are encoded and multiplexed onto the serial interface, reducing the serial data rate. The data enable input determines when the video or control data is serialized.
The MAX9217 pairs with the MAX9218 deserializer to form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair cable. Proprietary data encoding reduces EMI and provides DC balance. DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The LVDS output is internally terminated with 100Ω.
