The 92HD89B is a high fidelity, 4-channel audio codec compatible with the Intel High Definition (HD)
Audio Interface. The 92HD89B codec provides high quality, HD Audio capability notebooks and
desktops.
The 92HD89B is designed to meet or exceed premium logo requirements for Microsoft’s Windows
Logo Program (WLP) per Logo Point.
The 92HD89B provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. 92HD89B SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz.
The 92HD89B supports a wide range of notebook and desktop 4-channel configurations. The 2 inde-
pendent SPDIF output interfaces provides connectivity to Consumer Electronic equipment like Dolby
Digital decoders, powered speakers, mini disk drives or to a home entertainment system. Simulta-
neous HDMI and SPDIF output is possible.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HD89B has 5 General Purpose I/O (GPIO).
The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion and
removal for protection of notebook speakers.
The 92HD89B operates with a 3.3V digital supply and a 5V analog supply. It can also work with 1.5V
and 3.3V HDA signaling.
The 92HD89B is available in a 48-pin QFP or 40-pad QFN Environmental (ROHS) package.
Add an “8” to the end for tape and reel delivery.
