Overview
The DS90UB926Q-Q1 is a 5- to 85-MHz, 24-bit color FPD-Link III deserializer designed by Texas Instruments. This component, in conjunction with the DS90UB925Q-Q1 serializer, provides 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. The deserializer translates a parallel RGB video interface into a single-pair high-speed serialized interface, reducing interconnect size and weight while eliminating skew issues and simplifying system design.
