Overview
The DS90UR905Q-Q1 is a 5- to 65-MHz, 24-bit color FPD-Link II serializer produced by Texas Instruments. This component is part of the DS90UR90xQ-Q1 chipset, which includes both the serializer (DS90UR905Q-Q1) and the deserializer (DS90UR906Q-Q1). The serializer translates a parallel RGB video interface into a high-speed serialized interface over a single pair of wires, making it ideal for applications requiring reduced interconnect size, weight, and cost. It is particularly suited for automotive display systems due to its AEC-Q100 grade 2 qualification and robust ESD protection.
