Additional Details

The DS90UR903QSQ converts parallel RGB data into a serial stream, which is then transmitted over a shielded twisted pair cable. This reduces the number of wires needed and simplifies the interconnect between the graphics source and the display. The embedded clock eliminates the need for a separate clock signal, further reducing complexity and cost. The device incorporates features to minimize electromagnetic interference (EMI), which is crucial in sensitive applications like automotive systems. Being AEC-Q100 qualified, this serializer meets stringent automotive industry standards for reliability and performance in demanding environments.
