3 Description

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.
