TWO-CHANNEL, 20-BIT, AC’97 2.3 CODECS WITH HEADPHONE
DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING
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
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 STAC9752/9753 communicate 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, the STAC9752/9753 can be placed
on the motherboard, daughter boards, PCI, AMR, CNR,
MDC or ACR cards.
