DS90UB903Q/DS90UB904Q

10 - 43MHz 18 Bit Color FPD-Link III Serializer and

Deserializer with Bidirectional Control Channel

Single differential pair interconnect

Bidirectional control interface channel with I²C support

■

General Description

The DS90UB903Q/DS90UB904Q chipset offers a FPD-Link

III interface with a high-speed forward channel and a bidirec-

tional control channel for data transmission over a single

differential pair. The DS90UB903Q/904Q incorporates differ-

ential signaling on both the high-speed forward channel and

bidirectional control channel data paths. The Serializer/ De-

serializer 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 con-

verts 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, car-

rying asymmetrical bidirectional control channel information

in both directions. This single serial stream simplifies trans-

ferring a wide data bus over PCB traces and cable by elimi-

nating 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 con-

nector size and pins.

Embedded clock with DC Balanced coding to support AC-

coupled interconnects

Capable to drive up to 10 meters shielded twisted-pair

I²C compatible serial interface

feature to validate link integrity

Integrated termination resistors

■

1.8V- or 3.3V-compatible parallel bus interface

Single power supply at 1.8V

ISO 10605 ESD and IEC 61000-4-2 ESD compliant

Automotive grade product: AEC-Q100 Grade 2 qualified

Temperature range −40°C to +105°C

No reference clock required on Deserializer

Programmable Receive Equalization

In addition, the Deserializer inputs provide equalization con-

trol to compensate for loss from the media over longer dis-

tances. Internal DC balanced encoding/decoding is used to

support AC-Coupled interconnects.
