Two and Six-Channel 24-Bit, 192 kHz Audio Codec

OVERVIEW

DESCRIPTION

Two and six channel general purpose 24-bit, full duplex, SigmaTel’s STAC9460/62 are six and two-channel general-

audio codec for use in consumer applications.

purpose 24-bit, full duplex, audio codecs for use in con-

sumer applications. The STAC9460/62 incorporate Sigma-

Tel’s proprietary Sigma-Delta technology to achieve ADC

and DAC SNRs in excess of 100 dB. The DACs, and

ADCs are integrated with analog I/Os, which include two

differential analog and two MIC inputs. There are three

audio I²S inputs and an I²S digital output. The STAC9460/

62 communicates via a standard two-wire serial interface

providing simplicity in the audio system design. Packaged

in a 28-pin SSOP, the STAC9460 and STAC9462 require

minimal PCB space for implementation.

FEATURES

High performance Σ∆ technology

Two or six channels with independent

volume controls

24-bit full duplex stereo DACs

20-bit full duplex stereo ADC

The STAC9460 provides variable sample rate D-A and

A-D conversion, as well as analog processing. Sup-

ported audio sample rates include 32 kHz, 44.1 kHz,

48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz.

The digital interface communicates via a standard I²C

compatible serial interface and I²S digital audio inter-

face. The two variable sample rate ADC's provide

record capability from the microphone inputs or the dif-

ferential inputs. DAC's operate at 24-bit resolution with

the sample rate based on the Master Clock. The ADC

operates at 20-bit resolution and supplys full 24-bit filter

data.The STAC9460 supports three I²S digital audio

inputs and an I²S digital audio output. These digital I/O

options provide for a number of advance architectural

implementations, with volume controls and mute capa-

bilities built directly into the codec for each individual

channel. The output volume ranges from 0 dB to -

95 dB with .75 dB steps. For MIC input, the input vol-

ume ranges from 0 dB to 22.5 dB with 1.5 dB steps.

The STAC9460 also supports a single-line format.The

STAC9460 is designed primarily to support 6-channel

audio. True AC-3 playback can be achieved for 6-

speaker applications by taking advantage of the

STAC9460 architecture and combining it with the

appropriate processing. This product is ideal for home

theatre, DVD, karaoke, and set-top-box applications.
