The 92HD88 is a high fidelity, 4-channel audio codec compatible with the Intel High Definition (HD)
Audio Interface. The 92HD88 codec provides high quality, HD Audio capability to notebooks and
business desktops.
The 92HD88 is designed to meet or exceed premium logo requirements for Microsoft’s Windows
Logo Program as indicated in WLP 3.09.
The 92HD88 provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. 92HD88 SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. 92HD88 SPDIF input supports sample rates of 96kHz, 88.2kHz,
48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD88 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 mono amplifier is ideal for driving an integrated speaker in mobile, ultra-mobile,
business or desktop computers.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HD88 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 92HD88 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 92HD88 is available in a 40-pin QFN Environmental (ROHS) package.
