DESCRIPTION
The DS90UA101-Q1 Serializer, in conjunction with
the DS90UA102-Q1 Deserializer, provides a solution
for distribution of digital audio in multi-channel audio
systems. It transmits 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 DS90UA101-Q1 Serializer embeds the clock and
level shifts the signals to high-speed low-voltage
differential signaling. The device serializes up to eight
digital audio data inputs, 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.
