3 Description

The DS90UB924-Q1 deserializer, in conjunction with

a DS90UB921-Q1, DS90UB925Q-Q1, DS90UB927QQ1,

DS90UB929-Q1, DS90UB949-Q1, or

DS90UB947-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), 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.
