Description for the DS90UR903Q-Q1
The DS90UR903Q/DS90UR904Q chipset offers a FPD-Link II interface with a high-speed forward channel for data transmission over a single differential pair. The Serializer/ Deserializer pair is targeted for direct connections between graphics host controller and displays modules. This chipset is ideally suited for driving video data to displays requiring 18-bit color depth (RGB666 + HS, VS, and DE). The serializer converts 21 bit data over a single high-speed serial stream. This single serial stream simplifies transferring a wide data bus over PCB traces and cable by eliminating the skew problems between parallel data and clock paths. This significantly saves system cost by narrowing data paths that in turn reduce PCB layers, cable width, and connector size and pins.
The Deserializer inputs provide equalization control to compensate for loss from the media over longer distances. Internal DC balanced encoding/decoding is used to support AC-Coupled interconnects.
The Serializer is offered in a 40-pin WQFN package and the Deserializer is offered in a 48-pin WQFN package.
