Overview
The DS90UR905QSQE/NOPB, produced by Texas Instruments, is a 5- to 65-MHz, 24-bit color FPD-Link II serializer. This component is part of the DS90UR90xQ-Q1 chipset, which includes both the serializer (DS90UR905Q-Q1) and the deserializer (DS90UR906Q-Q1). The chipset is designed to translate a parallel RGB video interface into a high-speed serialized interface over a single pair of wires, simplifying system design by eliminating skew problems between clock and data signals. This solution reduces the number of connector pins, interconnect size, weight, and cost, while also easing PCB layout. The serializer embeds the clock, balances the data payload, and level shifts the signals to high-speed, low voltage differential signaling, supporting up to 24 inputs along with three video control signals (VS, HS, DE).
