The 92HD202 is a high fidelity, 8-channel audio CODEC compatible with the Intel High Definition
(HD) Audio Interface. The 92HD202 provides high quality, HD Audio capability to notebook and cost
sensitive desktop PC applications.
The 92HD202 incorporates IDT's proprietary Σ∆ technology to achieve a DAC SNR of up to 95 dB.
The higher performance and quality of IDT’s audio solutions brings consumer electronics level per-
formance to the notebook, desktop and media center PC.
The 92HD202 provide stereo 24-bit, full duplex resolution supporting sample rates up to 192 KHz by
the DAC and ADC. The 92HD202 DAC, ADC and SPDIF In/Out support sample rates of 96 KHz,
48 KHz and 44.1 KHz. Additional sample rates are supported by the driver software.
The 92HD202 supports all desired eight channel configurations, including switchable Headphone
Out, and Universal Jacks functionality for jack detection and re-tasking. The SPDIF interface pro-
vides connectivity to Consumer Electronic equipment, such as 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.
Microphone inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configura-
tions, the 92HD202 has up to four General Purpose I/O (GPIO) pins. The 92HD202 also provides a
single ended CD input for compatibility with Digital Rights Management (DRM) solutions and to sup-
port legacy OS issues.
The 92HD202 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 experi-
ence, and reduced implementation costs. An additional, lower power, headphone supports Port F.
The Universal Jack capabilities allow the CODEC to detect when audio devices are connected, and
allow the CODEC to be reconfigured to support these devices regardless of which port they are
