A new Serialiser/Deserialiser (SerDes) interface IC targeting automotive rear view safety systems has been developed by Intersil Corporation. The single chip transceiver solution simplifies system design by sending video data, bi-directional control information and power across a single shielded twisted pair (STP) cable. The product allows designers to lower system costs and simplify designs while improving transmission distance and video image quality.

The ISL76321 concentrates up to 16-bits wide video data and bi-directional I2C control information onto a single high-speed STP cable, and can transmit data in excess of 20 meters. Remote control of the far end of the link 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. This feature facilitates camera operation under changing conditions. Sending control data over the same cable as the video data eliminates unnecessary complexity in wiring looms and reduces weight.

A 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
