92HD73E1T5PRGIC1X

Overview

The 92HD73E1T5PRGIC1X is a low-power, high-fidelity 10-channel audio codec compatible with Intel High Definition Audio. It features five stereo DACs and two stereo ADCs with 24-bit resolution and sample rates up to 192kHz. The device supports full-duplex 7.1 audio, simultaneous VoIP, and dual independent SPDIF outputs for WLP compliance. It includes three integrated headphone amplifiers, nine stereo analog ports with presence detection, and digital microphone inputs. Designed for industrial temperature ranges (-40°C to +85°C), it operates on a 3.3V digital supply and a 5V analog supply within a 48-pin QFP package.

Feature Summary

• Supports ten channels with five stereo DACs and two stereo ADCs for full-duplex 7.1 audio and simultaneous VoIP
• Includes dual independent S/PDIF output converters for WLP compliant HDMI and consumer electronics connectivity
• Features three integrated headphone amplifiers and nine stereo analog ports with load impedance sensing
• Provides digital microphone input support and advanced power management with pop/click mitigation

Applications

• Desktop PC multimedia systems requiring 10-channel audio processing
• Multi-media notebook computers supporting full-duplex communication
• Home entertainment systems integrating consumer electronic equipment via SPDIF
• Industrial computing environments requiring extended temperature operation

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range specification before procurement. Confirm that the 48QFP package variant is required for dual SPDIF output functionality. Ensure compatibility with the TSI HD Sound software configuration tools for optimal performance tuning. Check current availability status as manufacturing cycles may vary.

Selection Notes

Select this component when a 10-channel HDA codec with industrial temperature rating is required. The 48QFP package is necessary for dual SPDIF outputs and additional GPIOs compared to the 40QFN version. Verify system power supplies match the 3.3V digital and 5V analog requirements. Consider the TSI SoftEQ and beamforming features if advanced audio processing is needed.

Part Context

This part belongs to the 92HD73E series of Ten Channel HD Audio Codecs by Tempo Semiconductor. It is specifically the industrial temperature grade variant housed in a 48-pin QFP package. It shares core architecture with commercial variants but differs in operating temperature range and package pinout capabilities.

Replacement Considerations

Direct replacements include other 92HD73E variants such as 92HD73E1X5PRGXC1X for commercial temperature or 92HD73E2X5NDGXC1X for the 40QFN package. Note that package differences affect available GPIOs and SPDIF output configurations.
