STAC9202
2-CHANNEL HIGH DEFINITION AUDIO CODEC WITH DUAL DIGITAL MICROPHONE INTERFACES
1.1.
2-CHANNEL HIGH DEFINITION AUDIO CODEC WITH DUAL DIGITAL MICROPHONE INTERFACES
Overview
The STAC9202 is a high fidelity, 2-channel, audio CODEC compliant with the High Definition Audio
(HD Audio) specification defined by Intel. The STAC9202 provides high quality, HD Audio capability
to notebook and cost sensitive desktop PC applications.
The STAC9202 incorporates IDT's proprietary ΣΔ technology to achieve a DAC SNR of 100 dB. The
higher performance and quality of IDT’s audio solutions brings consumer electronics level perfor-
mance to the notebook, desktop and media center PC.
The STAC9202 provides stereo, 24-bit, full duplex resolution supporting sample rates up to 192 KHz
by the DAC and ADC. The STAC9202 SPDIF_IN/SPDIF_OUT support sample rates of 96 KHz,
48 KHz and 44.1 KHz plus SPDIF_OUT supports 88.2 KHz. Additional sample rates are supported
by the driver software.
The STAC9202 supports flexible configurations including switchable Headphone Out and Universal
Jacks™ functionality for jack detection and re-tasking. The SPDIF interface provides connectivity to
Consumer Electronic equipment like Dolby Digital decoders, powered speakers, mini disk drives or
to a home entertainment system. All analog I/O pairs support LINE_IN, LINE_OUT and MIC.
MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the
STAC9202 has four General Purpose I/O (GPIO) pins. The STAC9202 also provides a single ended
CD input for compatibility with DRM solutions and to support legacy OS issues.
The STAC9202 integrates a headphone amplifier which is available on Ports A and D. The head-
phone amplifier is switchable between 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 to
the CODEC, and allow the CODECs to be reconfigured to support these devices, regardless of
which port they are plugged into. SPDIF input sensing is also supported. The fully parametric IDT
SoftEQ can be initiated upon headphone jack insertion and removal for protection of notebook
speakers.
The STAC9202 operates with a 3.3 V digital supply and a 3.3 V, 4 V and 5 V analog supply.
The STAC9202 is available in a 48-pin LQFP Environmental (ROHS) package.
The STAC9202 implements a direct interface to two digital microphones, supporting advanced beam
forming applications resulting in increased quality of applications requiring voice input.
Note: The Jack Detect circuit and component selection are critical for accurate detection of audio
jacks on individual ports. Please see the IDT STAC9202 reference design for circuit
implementation details.
