3 Description

The DS90UB913A-Q1 device offers an FPD-Link III

interface with a high-speed forward channel and a

bidirectional control channel for data transmission

over a single coaxial cable or differential pair. The

DS90UB913A-Q1 device incorporates differential

signaling on both the high-speed forward channel and

bidirectional control channel data paths. The

serializer/deserializer pair is targeted for connections

between imagers and video processors in an ECU

(Electronic Control Unit). This device is ideally suited

for driving video data requiring up to 12-bit pixel

depth plus two synchronization signals along with

bidirectional control channel bus.

Using TI’s embedded clock technology allows

transparent full-duplex communication over a single

differential pair, carrying asymmetrical-bidirectional

control channel information. 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. Internal DC-balanced
