DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING

•

5-wire AC-Link protocol compliance

20-bit SPDIF Output

Description

IDT's STAC9752/9753 are general purpose 20-bit, full

duplex, audio CODECs conforming to the analog

component specification of AC'97 (Audio CODEC 97

Component Specification Rev. 2.3). The STAC9752/9753

incorporate IDT's proprietary SD technology to achieve a

DAC SNR in excess of 90dB. The DACs, ADCs and mixer

are integrated with analog I/Os, which include four analog

line-level stereo inputs, two analog line-level mono inputs,

two stereo outputs, and one mono output channel. The

STAC9752/9753 include digital output capability for support

of modern PC systems with an output that supports the

SPDIF format. The STAC9752/9753 are standard

2-channel stereo CODECs. With IDT’s headphone

capability, headphones can be driven without an external

amplifier. The STAC9752/9753 may be used as a

secondary or tertiary CODECs, with STAC9700/21/44/56/

08/84/50/66 as the primary, in a multiple CODEC

configuration conforming to the AC'97 Rev. 2.3

specification. This configuration can provide the true

six-channel, AC-3 playback required for DVD applications.

The STAC9752/9753communicate via the five AC-Link

lines to any digital component of AC'97, providing flexibility

in the audio system design. Packaged in an AC'97

compliant 48-pin TQFP, theSTAC9752/9753 can be placed

on the motherboard, daughter boards, PCI, AMR, CNR,

MDC or ACR cards.
