Overview
The DS90UR906QSQE/NOPB is a 5- to 65-MHz, 24-bit Color FPD-Link II deserializer produced by Texas Instruments. This component is part of the FPD-Link II family, designed to translate a parallel RGB video interface into a high-speed serialized interface over a single pair of wires. This design simplifies system architecture by eliminating skew problems between clock and data, reducing the number of connector pins, and minimizing interconnect size, weight, and cost. The deserializer is automotive-grade, AEC-Q100 grade 2 qualified, and operates over a temperature range of –40°C to +105°C.
