1. DESCRIPTION
The STAC9227/9228/9229/9230 are high fidelity, 8-channel audio CODECs compatible with the Intel
High Definition (HD) Audio Interface. The STAC9227/9228/9229/9230 CODECs provide high quality,
HD Audio capability to notebook and cost sensitive desktop PC applications.
The STAC9227/9228/9229/9230 incorporate SigmaTel's proprietary technology to achieve a DAC
SNR in excess of 100 dB. The higher performance and quality of SigmaTel’s audio solutions brings
consumer electronics level performance to the notebook, desktop and media center PC.
The STAC9227/9228/9229/9230 provide stereo 24-bit, full duplex resolution supporting sample rates
up to 192 KHz by the DAC and ADC. The STAC9227/9228/9229/9230 SPDIF In/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 STAC9227/9228/9229/9230 support all desired eight channel configurations, including switch-
able Headphone Out, and Universal JacksTM functionality for jack detection and re-tasking. The
SPDIF interface provides connectivity to Consumer Electronic equipment like Dolby Digital decod-
ers, powered speakers, mini disk drives or to a home entertainment system. All analog I/O pairs sup-
port LINE_IN, LINE_OUT and MIC.
MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the
STAC9227/9228/9229/9230 has up to four General Purpose I/O (GPIO) pin. The STAC9227/9228/
9229/9230 also provide a single ended CD input for compatibility with DRM solutions and to support
legacy OS issues.
The STAC9227/9228/9229/9230 integrate a headphone amplifier which is available on Ports A, B
and D. The headphone amplifier is dedicated to these three 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 to allow the CODECs to be reconfigured to support these devices regardless of
which port they are plugged into the system. SPDIF input sensing is also supported. The fully para-
metric SigmaTel SoftEQ can be initiated upon headphone jack insertion and removal for protection of
notebook speakers. Note: The Jack Detect circuit and component selection are critical for accurate
detection of audio jacks on individual ports. Please see the SigmaTel STAC927x reference design
for circuit implementation details.
The STAC9227/9228/9229/9230 operate with a 3.3 V digital supply and a 3.3 V to 5 V analog supply.
The STAC9227/9228/9229/9230 are available in a 48-pin LQFP Environmental (ROHS) package.
