DESCRIPTION
The DS90UB903Q/DS90UB904Q chipset offers a
FPD-Link III interface with a high-speed forward
channel and a bidirectional control channel for data
transmission over a single differential pair. The
DS90UB903Q/904Q incorporates differential
signaling on both the high-speed forward channel and
bidirectional control channel data paths. 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) along with
bidirectional control channel bus. The primary
transport converts 21 bit data over a single high-
speed serial stream, along with a separate low
latency bidirectional control channel transport that
accepts control information from an I²C port. Using
TI’s embedded clock technology allows transparent
full-duplex communication over a single differential
pair, carrying asymmetrical bidirectional control
channel information in both directions. 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.
In addition, 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 lead in WQFN
and Deserializer is offered in a 48-pin WQFN
packages.
