8-CHANNEL HIGH DEFINITION AUDIO CODEC
PC AUDIO
1. DESCRIPTION
The 92HD206 is a high fidelity, 8-channel audio CODEC compatible with the Intel High Definition
(HD) Audio Interface. The 92HD206 CODEC provides high quality HD Audio capability to notebook
and cost sensitive desktop PC applications.
The 92HD206 incorporates IDT's proprietary technology to achieve a DAC SNR of 95dB. The higher
performance and quality of IDT’s audio solutions brings consumer electronics level performance to
the notebook, desktop and media center PC.
The 92HD206 provides stereo, 24-bit, full duplex resolution, supporting sample rates up to 192 KHz
by the DAC and ADC. The SPDIF In/Out supports 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 92HD206 supports all desired eight channel configurations, including switchable Headphone
Out, and Universal Jacksfunctionality for jack detection and re-tasking. The SPDIF interface pro-
vides connectivity to Consumer Electronic equipment like Dolby Digital decoders, powered speak-
ers, mini disk drives or a home entertainment systems. 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
92HD206 has up to three General Purpose I/O (GPIO) pins. The 92HD206 also provides a single
ended CD input for compatibility with DRM solutions and to support leg¬acy OS issues.
The 92HD206 integrates a headphone amplifier 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™ feature allows the CODEC to detect when audio devices are plugged in, and
for the CODEC 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 initi-
ated/disabled upon headphone jack insertion/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 92HD206 reference design for circuit implementation details.
The 92HD206 operates with a 3.3 V digital supply and a 5 V analog supply.
The 92HD206 is available in 48-pin LQFP Environmental (ROHS) packages.
