Intersil’s ISL76321 serialiser/deserialiser (SerDes) interface IC can be used to send video data, bi-directional control information and power across a single shielded twisted pair cable.

The transceiver concentrates up to 16-bits wide video data and bi-directional I2C control information onto a single twisted-pair cable, and can transmit data in excess of 20m.

Remote control of the far end of the link, an attractive feature of the ISL76321, allows a controller to access an imager via its I2C interface through which operating modes and adjustments, such as exposure and windowing, can be made.

In a automotive camera sensor application, the camera link comprises a pair of ISL76321s connected via a single STP cable to establish a high resolution, serial data link between a remote video camera and a central control unit.

This interface transceiver accommodates a wide pixel clock range from 8MHz to 50MHz, and raw data rates up to 1000Mbit/s.

The ISL76321 uses industry standard 8b/10b encoding to improve signal integrity as well as giving the link hot plugging capability.
