DATASHEET

10-CHANNEL HIGH DEFINITION AUDIO CODEC

Description

The STAC927x “Red River” is a family of Theater Quality

10-channel audio CODECs that enable systems with 7.1

audio playing simultaneously with VoIP or another stereo

audio stream. IDT's proprietary

Σ∆

technology provides

high fidelity with an estimated DAC SNR up to 105dB. Up to

four digital microphones are supported enabling high

quality voice input for increased usability of voice

applications.

STAC9271/9272/9273/9274

•

Digital PC Beep to all outputs

+3.3 V to +5 V analog power supply options

Environmental 48-pin LQFP package

Software Support

•

SKPI (Kernel Processing Interface)

•

Enables plug-ins that can operate globally on all audio

streams of the system

Constant, system-level effects tuned to optimize a

particular platform can be combined with user-mode

“presets” tailored for specific acoustical environments

and applications

System-level effects automatically disabled when

external connections made

Enables improved voice articulation

Compressor/limiter allows higher average noise level

without resonances
