3 Description

The DS90UB925Q-Q1 serializer, in conjunction with

the DS90UB926Q-Q1 deserializer, provides a

complete digital interface for concurrent transmission

of high-speed video, audio, and control data for

automotive display and image sensing applications.

The chipset is ideally suited for automotive video-

display systems with HD formats and automotive

vision systems with megapixel resolutions. The

DS90UB925Q-Q1 incorporates an embedded

bidirectional control channel and low latency GPIO controls. This chipset translates a parallel interface

into a single pair high-speed serialized interface. The

serial bus scheme, FPD-Link III, supports full duplex

of high-speed video data transmission and

bidirectional control communication over a single differential link. Consolidation of video data and

control over a single differential pair reduces the

interconnect size and weight, while also eliminating

skew issues and simplifying system design.

The DS90UB925Q-Q1 serializer embeds the clock,

DC scrambles & balances the data payload, and level

shifts the signals to high-speed low voltage differential signaling. Up to 24 data bits are serialized

along the video control signals.

Serial transmission is optimized by a user selectable de-emphasis. EMI is minimized by the use of low

voltage differential signaling, data scrambling and

randomization and spread spectrum clocking

compatibility.
