Overview
The DS90UR906QSQX/NOPB is a deserializer component from Texas Instruments, part of the DS90UR90xQ-Q1 chipset. This device is designed to deserialize high-speed serialized video data transmitted over a single pair of wires, converting it back into a parallel RGB video interface. It is particularly suited for automotive applications, such as navigation and entertainment displays, due to its compliance with the AEC-Q100 grade 2 temperature range of –40°C to +105°C.
The DS90UR906Q-Q1 deserializer works in conjunction with the DS90UR905Q-Q1 serializer, together forming the FPD-Link II interface. This interface simplifies system design by reducing skew issues, the number of connector pins, and overall interconnect size, weight, and cost.
