The ISL76321 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
bidirectional 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.

Features
• 16-bit RGB transport over a single differential pair
• 6MHz to 50MHz pixel clock rates
• AEC-Q100 qualified component
• Bi-directional auxiliary data transport without extra bandwidth
and over the same differential pair
• Hot-plugging with automatic resynchronization every HSYNC
• I2C bus mastering to the remote side of the link with a
controller on either the serializer or deserializer
• Selectable clock edge for parallel data output
• DC-balanced with industry standard 8b/10b line code allows
AC-coupling, providing immunity against ground shifts
• 16 programmable settings each for transmitter amplitude
boost and pre-emphasis and receiver equalization, allow for
longer cable lengths and higher data rates
• Slew rate control and spread spectrum capability on outputs
reduce the potential for EMI
• Same device for serializer and deserializer simplifies inventory

Applications
• Video entertainment systems
• Remote cameras
