DS90UA101-Q1 Multi-Channel Digital Audio Link

Check for Samples: DS90UA101-Q1

FEATURES

APPLICATIONS

•

Digital Audio Serializer

Flexible Digital Audio Inputs, supporting I²S

(Stereo) or TDM (Multi-Channel) Formats

•

Automotive Infotainment Systems

Active Noise Cancellation Systems

Distributed Multi-Channel Audio Systems

•

Coaxial or Single Differential Pair Interconnect

High Speed Serial Output Interface

Very Low Latency (<15µs)

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.

Bidirectional Control Interface Channel with

I²C-Compatible Serial Control Bus

Supports up to 8 Stereo I²S or TDM Audio

Inputs

•

Supports Audio System Clocks from 10MHz to

50MHz

•

Single 1.8V Supply

1.8V or 3.3V I/O Interface

4/4 Dedicated General Purpose Inputs/Outputs

AC-Coupled STP or Coaxial Cable up to 15m

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.

DC-Balanced & Scrambled Data w/ Embedded

Clock

•

Automotive Grade Product: AEC-Q100 Grade 2

Qualified

•

Temperature Range: -40°C to 105°C

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.

ISO 10605 and IEC 61000-4-2 ESD Compliant
