Product details
Overview
92HD73E2X5NDGXC1X from Integrated Device Technology is a 10-channel HD Audio codec IC compliant with Intel High Definition Audio Interface, delivering stereo 24-bit resolution at sample rates up to 192kHz. It integrates dual SPDIF input/output capability, three headphone amplifiers, nine stereo analog ports with presence detection, and supports full-duplex 7.1 audio plus simultaneous VoIP in notebook and desktop PC audio subsystems.
For engineers reviewing the 92HD73E2X5NDGXC1X datasheet, 92HD73E2X5NDGXC1X pinout, 92HD73E2X5NDGXC1X application, or 92HD73E2X5NDGXC1X equivalent, key selection criteria include SPDIF I/O configuration, 40QFN package constraints (3.3V-only HDA signaling), VREF bias options, analog mixer flexibility, and Microsoft WLP 3.09/4 compliance for premium audio certification.
Technical Context
The 92HD73E2X5NDGXC1X implements an Intel HDA-compliant audio function group (AFG) with two stereo ADCs and five stereo DACs, supporting independent SPDIF input and single SPDIF output. Its analog front-end includes programmable microphone boost (0/10/20/30dB), adjustable VREF outputs for biasing, and a high-performance analog mixer with ±34.5dB input gain control and master volume scaling.
Power management follows HDA specification states (D0–D3), with GPIOs, VREF outputs, and analog mixer active in D0/D1/D2 but disabled in D3. The 40QFN package supports only 3.3V HDA signaling and lacks digital microphone inputs (DMIC0/DMIC1), second SPDIF output, and four additional GPIOs present in the 48QFP variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Audio Channels | 10-channel (5 stereo DACs + 2 stereo ADCs) enabling full-duplex 7.1 surround audio with simultaneous VoIP streaming. |
| Resolution & Sample Rate | 24-bit stereo resolution with DAC/ADC sample rates up to 192kHz - meets high-fidelity playback and recording requirements. |
| SPDIF Support | Single SPDIF input and single SPDIF output (pin 40); supports 44.1/48/88.2/96kHz rates - enables direct connection to Dolby Digital decoders or powered speakers. |
| Package & Signaling | 40-pin QFN RoHS package; 3.3V-only HDA signaling - eliminates voltage-level negotiation logic required in dual-voltage 48QFP variants. |
| Analog I/O Ports | 9 stereo analog ports with jack presence detection and load impedance sensing - simplifies auto-configuration of headphones, line-outs, and mic inputs. |
| Headphone Drivers | 3 integrated headphone amplifiers capable of driving 32Ω loads - reduces BOM count and PCB area versus discrete amplifier solutions. |
| Microphone Bias | 3 adjustable VREF output pins (0/10/20/30dB boost programmable) - supports electret condenser microphones across varying sensitivity and noise floor requirements. |
Pinout & Package
92HD73E2X5NDGXC1X is housed in a 40-pin QFN RoHS package (7mm × 7mm, 0.5mm pitch) with exposed thermal pad. Pin assignments are defined per datasheet Section 7.2 and Figure 13, supporting 3.3V-only HDA signaling, single SPDIF I/O, and 9 analog port interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVDD, DVDD | Analog & digital power supply | 5V analog rail (AVDD) and 3.3V digital rail (DVDD); no 1.5V support - constrains host platform voltage architecture. |
| SPDIF_IN (Pin 3) | Digital audio input | Accepts consumer SPDIF voltage levels directly - eliminates need for external level-shifting receiver ICs. |
| SPDIF_OUT (Pin 40) | Digital audio output | Drives SPDIF-format data at supported sample rates; internal pull-down enabled when inactive - ensures clean signal state during power transitions. |
| VREF0–VREF2 | Microphone bias reference | Three independently configurable VREF outputs - enable simultaneous biasing of multiple electret mics with tailored gain settings. |
| SENSE_A / SENSE_B | Jack presence detection | Dedicated sense lines for multi-port plug detection (A–D on SENSE_A; E–H on SENSE_B) - enables OS-level auto-jack routing without firmware polling. |
| HDA_SDIN / HDA_SDOUT | HDA link interface | Serial bidirectional data interface compliant with Intel HD Audio Link timing - connects directly to host controller's HDA bus. |
Key Features
| Feature | Design Value |
|---|---|
| Microsoft WLP 3.09/4 Compliance | Validated for Windows Logo Program premium audio certification - required for OEM branding on Windows 7/8 systems. |
| Pop/Click Mitigation | Output ports remain biased during power state transitions (D0–D3) - prevents audible transients when resuming from sleep or changing stream activity. |
| Flexible Analog Mixer | Independent ±34.5dB gain (1.5dB steps) per input + master volume control - enables precise analog-level mixing of CD, PC beep, and port signals before ADC digitization. |
| Dual ADC Multiplexers | Two 12-input muxes (ADC0/ADC1) with 0–+22.5dB record gain - supports dynamic routing of mic, line-in, or mixer output to either ADC path. |
| Jack Presence Detection | Hardware-assisted plug detection across 9 ports using SENSE_A/B/C - reduces CPU overhead and enables instant OS-level audio device reconfiguration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HD Audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 92HD73E1X5PRGXC1X | 48QFP package; supports dual SPDIF outputs, 1.5V/3.3V HDA signaling, DMIC inputs, and 4 VREF outputs. | Required for HDMI+SPDIF simultaneous output or quad digital mic array support - not feasible with 40QFN 92HD73E2X5NDGXC1X. | Select when dual SPDIF, flexible voltage signaling, or digital mic interface is mandatory; otherwise 92HD73E2X5NDGXC1X offers smaller footprint and lower cost. |
| ALC269VC | Realtek HD Audio codec in 48QFP; supports 24-bit/192kHz, single SPDIF I/O, 3 headphone amps, but lacks WLP 3.09/4 certification and advanced analog mixer features. | Suitable for cost-sensitive mainstream notebooks where WLP logo is not required and analog mixing complexity is lower. | Choose for non-WLP platforms prioritizing vendor driver maturity over premium certification; verify jack detect and pop/click mitigation performance against 92HD73E2X5NDGXC1X. |
Compared with 92HD73E1X5PRGXC1X, the 92HD73E2X5NDGXC1X trades dual SPDIF, DMIC, and voltage-flexible signaling for a smaller 40QFN footprint and lower thermal profile. Against ALC269VC, it delivers verified WLP 3.09/4 compliance and superior analog mixer programmability - critical for OEM audio tuning and certification.

FAQ
What is the maximum supported sample rate for DAC and ADC in the 92HD73E2X5NDGXC1X?
The 92HD73E2X5NDGXC1X supports stereo 24-bit resolution with DAC and ADC sample rates up to 192kHz. This capability is confirmed in the datasheet Section 1.1 and Table 16, enabling high-resolution audio playback and recording for professional and consumer multimedia applications. The 92HD73E2X5NDGXC1X maintains this performance across all analog ports and SPDIF interfaces.
Does the 92HD73E2X5NDGXC1X support Microsoft Windows Logo Program (WLP) certification?
Yes, the 92HD73E2X5NDGXC1X is designed to meet or exceed Microsoft WLP 3.09 and revision 4 requirements, as explicitly stated in datasheet Section 1.1. This certification enables OEMs to qualify desktop and notebook platforms for Windows 7/8 premium audio branding. The 92HD73E2X5NDGXC1X achieves this through hardware-level features including pop/click mitigation, jack presence detection, and full-duplex 7.1 audio support.
How many SPDIF interfaces does the 92HD73E2X5NDGXC1X provide, and what are their capabilities?
The 92HD73E2X5NDGXC1X provides one SPDIF input (Pin 3) and one SPDIF output (Pin 40), both supporting sample rates of 44.1kHz, 48kHz, 88.2kHz, and 96kHz. Unlike the 48QFP variant, the 40QFN-based 92HD73E2X5NDGXC1X does not include a second SPDIF output. The SPDIF_IN accepts consumer-level voltage directly, eliminating external receiver ICs, while SPDIF_OUT drives standard coaxial/optical transmitters.
What are the power supply requirements for the 92HD73E2X5NDGXC1X?
The 92HD73E2X5NDGXC1X requires a 5V analog supply (AVDD) and a 3.3V digital supply (DVDD). It does not support 1.5V HDA signaling - a capability exclusive to the 48QFP package variants. The 40QFN package enforces 3.3V-only operation for HDA link signaling, simplifying host board power design but limiting voltage flexibility compared to the 48QFP family members.
Can the 92HD73E2X5NDGXC1X drive 32Ω headphones directly?
Yes, the 92HD73E2X5NDGXC1X integrates three dedicated headphone amplifiers optimized to drive 32Ω loads, as specified in datasheet Section 1.3.2 and Table 1. Each amplifier supports full-scale output of 1V rms and includes pop/click suppression circuitry. This eliminates the need for external headphone drivers in space-constrained notebook and mini-PC designs, reducing BOM cost and PCB area.
