10 - 43MHz 18 Bit Color FPD-Link II Serializer and
Deserializer
General Description
The DS90UR903Q/DS90UR904Q chipset offers a FPD-Link
II interface with a high-speed forward channel for data trans-
mission over a single differential pair. The Serializer/ Deseri-
alizer 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 com-
pensate for loss from the media over longer distances. Inter-
nal DC balanced encoding/decoding is used to support AC-
Coupled interconnects.
The Serializer is offered in a 40-pin lead in LLP and Deseri-
alizer is offered in a 48-pin LLP packages.
