The DS92LX1621SQE/NOPB is a DC-balanced bi-directional Control Serializer chipset offers a Channel Link III interface with a high-speed forward channel and a full-duplex back channel for data transmission over a single differential pair. The serializer is targeted for direct connections between automotive camera systems and host controller/electronic control unit (ECU). The primary transport sends 16 bits of image data over a single high-speed serial stream together with a low latency bi-directional control channel transport that supports I²C. Included with the 16-bit payload is a selectable data integrity option for CRC (cyclic redundancy check) or parity bit to monitor transmission link errors. Using TIs embedded clock technology allows transparent full-duplex communication over a single differential pair, carrying asymmetrical bi-directional control information without the dependency of video blanking intervals.
