Overview
The DS90UB927QSQ/NOPB is a 5-MHz to 85-MHz 24-bit Color FPD-Link III serializer produced 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 HD video formats and megapixel vision systems. The serializer works in conjunction with deserializers such as the DS90UB928Q-Q1 or DS90UB926Q-Q1 to translate a FPD-Link video interface into a single-pair high-speed serialized interface, minimizing interconnect size and weight while simplifying system design.
