DS90UA102-Q1 (ACTIVE) Multi-Channel Digital Audio Deserializer

 

Description

The DS90UA102-Q1 Deserializer, in conjunction with the DS90UA101-Q1 Serializer, provides a solution for distribution of digital audio in multi-channel audio systems. It receives a high-speed serialized interface with an embedded clock over a single shielded twisted pair or coaxial cable. The serial bus scheme supports high speed forward data transmission and low speed bidirectional control channel over the link. Consolidation of digital audio, general-purpose IO, and control signals over a single differential pair reduces the interconnect size and weight, while also reducing design challenges related to skew and system latency.

The DS90UA102-Q1 Deserializer extracts the clock and level shifts the signals from high-speed low voltage differential signaling to single-ended LVCMOS. The device outputs up to eight digital audio data channels, word/frame sync, bit clock, and system clock.

Four dedicated general purpose input pins and four general purpose output pins allow flexible implementation of control and interrupt signals to and from remote devices.

Adaptive equalization of the serial input stream provides compensation for transmission medium losses of the cable and reduces medium-induced deterministic jitter.
