SINGLE CHIP PC AUDIO SYSTEM, CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO
1. DESCRIPTION
1.1. Overview
The 92HD81 is a high fidelity, 4-channel audio codec compatible with the Intel High Definition (HD)
Audio Interface. The 92HD81 codec provides high quality, HD Audio capability notebooks and busi-
ness desktops.
The 92HD81 is designed to meet or exceed premium logo requirements for Microsoft’s Windows
Logo Program (WLP) 3.09 and revisions 4/5 as indicated in WLP 3.09.
The 92HD81 provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. 92HD81 SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. 92HD81 SPDIF input supports sample rates of 96kHz, 88.2kHz,
48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD81 supports a wide range of notebook and business desktop 4-channel configurations.
The 2 independent SPDIF output interfaces provides connectivity to Consumer Electronic equipment
like Dolby Digital decoders, powered speakers, mini disk drives or to a home entertainment system.
Simultaneous HDMI and SPDIF output is possible.
An integrated BTL stereo amplifier is ideal for driving integrated speakers in mobile and ultra-mobile
computers. For desktop computers or mobile computers using only one speaker, the BTL output
stage may be configured to support a single mono speaker.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HD81 has 3 General Purpose I/O (GPIO).

The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. Load impedance sensing helps identify attached peripherals for easy set-up and a bet-
ter user experience. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion
and removal for protection of notebook speakers.
The 92HD81 operates with a 1.5V, 1.8V or 3.3V digital supply and a 5V analog supply. It can also
work with 1.5V and 3.3V HDA signaling; the correct signalling level is selected dynamically based on
the power supply voltage on the DVDD-IO pin.
The 92HD81 is available in a 48-pin QFN Environmental (ROHS) package.
