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
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.
