Overview
The DS90UB927Q-Q1 is a 5-MHz to 85-MHz 24-bit color FPD-Link III serializer developed by Texas Instruments. This device is designed to provide a complete digital interface for the concurrent transmission of high-speed video, audio, and control data. It is particularly suited for automotive display and image sensing applications, including navigation systems, rear seat entertainment, and driver assistance devices. The serializer works in conjunction with the DS90UB928Q-Q1 or DS90UB926Q-Q1 deserializer to form a full duplex, high-speed serialized interface over a single differential pair, minimizing interconnect size and weight while simplifying system design.
