10.1 Application Information

The DS90UB914A was designed as a deserializer to support automotive camera designs. Automotive cameras are often located in remote positions such as bumpers or trunk lids, and a major component of the system cost is the wiring. For this reason it is desirable to minimize the wiring to the camera. This chipset allows the video data, along with a bidirectional control channel, and power to all be sent over a single coaxial cable. The chipset is also able to transmit over STP and is pin-to-pin/backwards compatible with the DS90UB914Q.
