Overview
The DS90UB927QSQE/NOPB is a 5-MHz to 85-MHz 24-bit Color FPD-Link III serializer produced by Texas Instruments. This device is designed for automotive video display systems and vision systems, supporting high-definition (720p) digital video formats. It integrates a bidirectional control channel and low latency GPIO controls, making it ideal for concurrent transmission of high-speed video, audio, and control data. The serializer translates the FPD-Link video interface into a single-pair high-speed serialized interface, reducing interconnect size and weight while simplifying system design.
