92HD73E2X5NDGXC1X

Overview

The 92HD73E is a high-fidelity, low-power optimized audio codec compatible with Intel High Definition Audio. It features ten channels comprising five stereo DACs and two stereo ADCs with 24-bit resolution. The device supports sample rates up to 192kHz for both playback and capture. It includes dual independent SPDIF outputs and one SPDIF input. The 48QFP package supports 1.5V and 3.3V HDA signaling selection, while the 40QFN package supports 3.3V only. Operating conditions include a 3.3V digital supply and a 5V analog supply.

Feature Summary

• Supports full-duplex 7.1 audio and simultaneous VoIP streams
• Includes three integrated headphone amplifiers and nine stereo analog ports with presence detect capability
• Features Microsoft Windows Logo Program compliance and pop/click mitigation
• Provides software support for beamforming, acoustic echo cancellation, and noise suppression

Applications

• Multimedia notebook computers
• Desktop PC systems
• Home entertainment systems requiring HDMI/SPDIF connectivity

Procurement Notes

Verify the specific suffix against the datasheet orderable part numbers list. Confirm whether the required package is the 48-pin QFP or the 40-pin QFN variant. Ensure the voltage signaling requirements match the selected package capabilities before finalizing procurement.

Selection Notes

Select the 48QFP package if runtime selection between 1.5V and 3.3V HDA signaling is required. Choose the 40QFN package for designs strictly utilizing 3.3V signaling. Verify that the application requires the additional GPIOs and digital microphone inputs available exclusively on the 48QFP version.

Part Context

This component belongs to the IDT 92HD73E series of high-definition audio codecs. It is designed as a direct replacement for legacy audio solutions in modern computing platforms requiring multi-channel audio processing and consumer electronics integration.

Replacement Considerations

Compatible substitutes include the 92HD73E1X5PRGXC1X (48QFP) and the 92HD73E2X5NDGXC1X (40QFN). Verify pin compatibility and package dimensions when transitioning between these variants.
