1. DESCRIPTION
IDT™
4-CHANNEL HD AUDIO CODEC WITH QUAD DIGITAL MICROPHONE INTERFACE
STAC9204/9205
4-CHANNEL HD AUDIO CODEC WITH QUAD DIGITAL MICROPHONE INTERFACE
1.1.
Overview
The STAC9204/9205 are high fidelity, 4-channel HD Audio CODECs that enable 2.0 Audio with
simultaneous real-time communication such as VoIP, conferencing, voice command and control, etc.
Up to four digital microphones are supported enabling high quality voice input for increased usability
of voice applications.
The STAC9204/9205 incorporate IDT's proprietary SD technology to achieve a DAC SNR in excess
of 100dB. The higher performance and quality of IDT’s audio solutions brings consumer electronics
level performance to the notebook, desktop and media center PC.
The STAC9204/9205 provide stereo, 24-bit, full duplex resolution, supporting sample rates up to
192 KHz by the DAC and ADC. The STAC9204/9205 SPDIF In/Out supports sample rates of
96 KHz, 48 KHz and 44.1 KHz plus SPDIF OUT supports 88.2 KHz and 192 KHz. Additional sample
rates are supported by the driver software.
The STAC9204/9205 support all desired four channel configurations, including switchable Head-
phone (HP) Out and Universal Jacks™ functionality for jack detection and re-tasking. The SPDIF
interface provides connectivity to consumer electronic equipment like Dolby Digital decoders, pow-
ered speakers and mini-disk drives, or to a home entertainment system. All analog I/O pairs support
LINE_IN, LINE_OUT and MIC. (Port D only supports fixed-function microphone.)
MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the
STAC9204/9205 have five General Purpose I/O (GPIO) pins. The STAC9204/9205 also provide sin-
gle ended CD input for compatibility with DRM solutions and to support legacy OS issues.
The STAC9204/9205 integrate two headphone amplifiers which are available on Ports A and D. The
headphone amplifiers are dedicated to these two outputs for increased flexibility, enhanced user
experience, and reduced implementation costs.
The Universal Jack capabilities allow the CODECs to detect when audio devices are connected, and
allow the CODECs to be reconfigured to support these devices regardless of which port they are
connected to. SPDIF input sensing is also supported. The fully parametric IDT SoftEQ can be initi-
ated upon headphone jack insertion and removal for protection of notebook speakers.
The STAC9204/9205 operate with a 3.3 V digital supply and either 3.3 V, 4 V, 4.5 V or 5 V analog
supply. They also support 1.5 V and 3.3 V HDA signaling; the correct voltage is selected dynamically
based on the value of the appropriate pin.
The STAC9204/9205 are available in a 48-pin LQFP or a 48-pad QFN Environmental (ROHS) pack-
age.
