Transceiver enable high-def video over unshielded cables in cars

The new integrated circuits use ADI’s Car Camera Bus (C2B) technology, enabling significant savings in weight, bulk, cost, and reduce cable-routing constraints when compared to other automotive link solutions.

C2B transceivers are defined and designed specifically for automotive applications, which means that along with supporting the necessary high visual quality over the unshielded infrastructure, care was also taken with on-chip EMC/EMI mitigation techniques enabling full compliance to the rigorous industry mandates for EMC, EMI, and ESD robustness. The performance of the cable-compensation design supports 30-meter cable runs with multiple in-line connections for resolutions up to 2 megapixels at 30 Hz or 1 megapixel at 60 Hz.

The ADV7990/91 and ADV7380/81 transceivers feature negligible latency along with uncompressed transmission; the bidirectional control channel uses the same cable and thus incurs no additional costs. These devices support a 75-MHz pixel rate (75 MHz Y, 75 MHz C) “frozen frame” detection while the bidirectional control function supports I2C, interrupt/status and general-purpose I/O (GPIO).
