3 Description

The DS90UB91xQ-Q1 chipset offers an FPD-Link III

interface with a high-speed forward channel and a

bidirectional control channel for data transmission

over a single differential pair. The DS90UB91xQ-Q1

chipsets incorporate differential signaling on both the

high-speed forward channel and bidirectional control

channel data paths. The serializer and deserializer pair is targeted for connections between imagers and

video processors in an electronic control unit (ECU).

This chipset is ideally suited for driving video data

that requires up to 12-bit pixel depth plus two

synchronization signals along with bidirectional

control channel bus.

There is a multiplexer at the deserializer to choose

between two input imagers. The deserializer can

have only one active input imager. The primary video transport converts 10- and 12-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 and is

independent of video blanking period.
