3 Description

The DS90UB928Q-Q1 deserializer, in conjunction

with a DS90UB925Q-Q1 or DS90UB927Q-Q1

serializer, provides a solution for distribution of digital

video and audio within automotive infotainment

systems. The device converts a high-speed serialized

interface with an embedded clock, delivered over a

single signal pair (FPD-Link III), to four LVDS

data/control streams, one LVDS clock pair (OpenLDI

(FPD-Link)), and I2S audio data. The serial bus

scheme, FPD-Link III, supports high-speed forward

channel data transmission and low-speed full duplex

back channel communication over a single differential

link. Consolidation of audio, video data and control

over a single differential pair reduces the interconnect

size and weight, while also eliminating skew issues

and simplifying system design.

Adaptive input equalization of the serial input stream

provides compensation for transmission medium

losses and deterministic jitter. EMI is minimized by

the use of low voltage differential signaling.
