3 Description
The DS90UB924-Q1 deserializer, in conjunction with
a DS90UB921-Q1, DS90UB925Q-Q1, DS90UB927Q-
Q1, 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.
