92HD73E
Ten Channel HD Audio Codec
1. DESCRIPTION
1.1.
Overview
The 92HD73E is a high fidelity, 10-channel audio codec compatible with the Intel High Definition
(HD) Audio Interface. The 92HD73E codec provides high quality, HD Audio capability to desktop
and multi-media notebook.
The 92HD73E is designed to meet or exceed premium logo requirements for Microsoft’s Windows
Logo Program (WLP) 3.09 and revisions 4 as indicated in WLP 3.09.
The 92HD73E provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. 92HD73E SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. 92HD73E SPDIF input supports sample rates of 96kHz, 88.2kHz,
48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD73E supports a wide range of desktop and consumer 8/10 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.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HD73E has 8 General Purpose I/O (GPIO) in the 48QFP package.
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 92HD73E 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 correct signalling level is selected dynamically based on the power sup-
ply voltage on the DVDD-IO pin in the 48QFP package. The 40QFN package allows for 3.3V HDA
signalling.
