Product details
Overview
IDT92HD71B5X3NLGXB3X8 from IDT (now part of Renesas) is a low-power, 4-channel HD Audio codec IC compliant with Intel High Definition Audio Interface. It delivers stereo 24-bit DAC/ADC conversion at up to 192 kHz, integrates dual S/PDIF outputs, supports digital microphone arrays, and provides mono sub-woofer output - all in a 48-pin QFN package for notebook and business desktop PC audio subsystems.
For engineers reviewing the IDT92HD71B5X3NLGXB3X8 datasheet, IDT92HD71B5X3NLGXB3X8 pinout, IDT92HD71B5X3NLGXB3X8 application, or IDT92HD71B5X3NLGXB3X8 equivalent, key selection considerations include HDA link compatibility, WLP 3.09 compliance, dual SPDIF output capability, runtime-selectable 1.5V/3.3V signaling, and integrated headphone amplifier performance.
Technical Context
The IDT92HD71B5X3NLGXB3X8 implements a full-duplex Intel HD Audio interface with two independent stereo DACs (DAC0/DAC1) and two stereo ADCs (ADC0/ADC1), plus dedicated mono output and digital microphone input paths. Its architecture supports dynamic stream switching and jack insertion detection via configurable GPIO and unsolicited response handling.
It features dual independent S/PDIF transmitters compliant with WLP HDMI/SPDIF requirements, adjustable VREF outputs for microphone biasing, and flexible power management with pop/click mitigation. The codec supports 1.5V and 3.3V HDA signaling modes selected at runtime, enabling interoperability across diverse platform voltage domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HD Audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Realtek ALC269VC | Single SPDIF output; no dual S/PDIF; lower max sample rate (96 kHz); lacks digital mic input support | Targeted at cost-sensitive mainstream notebooks without Dolby certification or HDMI audio requirements | Select when dual SPDIF, 192 kHz, or digital mic inputs are not required - lower BOM cost but reduced feature set |
| Conexant CX20752 | Supports only 16-bit/48 kHz PCM over HDA link; no 24-bit/192 kHz capability; no WLP 3.09 compliance | Designed for basic voice-centric thin clients and entry-level desktops with minimal audio fidelity requirements | Choose only for legacy platforms where high-resolution audio and Microsoft logo compliance are unnecessary |
