92HD202
8-CHANNEL HIGH DEFINITION AUDIO CODEC
PC AUDIO
• Mic with 0/10/20/30/40 dB Mic boost³
• Port E (pins 14 & 15) can be used for:
• Line In
• Mic with 0/10/20/30/40 dB Mic boost³
Note¹: On the 92HD202, only one function can be selected on each pin pair at a time. For example,
a pin pair cannot be configured as an input and output at the same time. Configuration can be
changed at any time.
Note²: Headphone capabilities are provided on ports A, D and F. Do NOT put headphone loads on
more than one port at a time. Port F (pins 16 & 17) can drive 32 ohm headphones, but is designed to
provide less power than the headphone amplifiers on ports A (pins 39 & 41) and D (pins 35 & 36).
Note³: 40dB Microphone boost is not recommended.
3.3. SPDIF Input
SPDIF IN can operate at 44.1 KHz, 48 KHz or 96 KHz, and implements internal Jack Sensing.
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.
Advanced features such as record slot select and SPDIF_IN routing to the DAC allows for simulta-
neous record and play.
3.4. SPDIF Output
SPDIF Output can operate at 44.1 KHz, 48 KHz, and 96 KHz as defined in the Intel High Definition
Audio Specification with resolutions up to 24 bits. This insures compatibility with all consumer audio
gear and allows for convenient integration into home theater systems and media center PCs.
