8-CHANNEL HIGH DEFINITION AUDIO CODEC
MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the
STAC9220/9221/9223 have three General Purpose I/O (GPIO) pins. The STAC920/9221/9223 also
provide a single ended CD input for compatibility with DRM solutions and to support legacy OS
issues.
The STAC9220/9221/9223 integrates a headphone amplifier which is available on Ports A and D.
The headphone amplifier is switchable between these two outputs for increased flexibility, enhanced
user experience, and reduced implementation costs. An additional headphone is supported on
Port F.
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 IDT 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 IDT STAC922x reference design for circuit
implementation details.
The STAC9220/9221/9223 operates with a 3.3 V digital supply and is available in either 5 V analog
supply or 3.3 V analog supply options.
The STAC9220/9221/9223 are available in a 48-pin LQFP package. The 48-pin LQFP is only avail-
able in the Environmental package (Pb-free).
The STAC9220/9221/9223 are supported with IDT’s high quality software solutions which include
drivers for all major Windows operating systems from Microsoft, parametric SoftEQ, and Digital
Rights Management. Third party plug-in capability is easily achieved with the IDT Kernel Processing
Interface, to support high-valued, third party technologies like SRS WOW
, Knowles
Microphone
Beam Forming, Waves MaxxBASS
, Dolby Headphone
, Dolby ProLogic II
and Dolby Virtual
Speaker
and more.
