Renesas 92HD73E2X5NDGXC1X

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 192 kHz. It integrates two stereo ADCs and five stereo DACs, supports SPDIF input and single SPDIF output, and operates with 3.3 V digital supply for multimedia notebook and desktop PC audio subsystems.

For engineers reviewing the 92HD73E2X5NDGXC1X datasheet, 92HD73E2X5NDGXC1X pinout, 92HD73E2X5NDGXC1X application, or 92HD73E2X5NDGXC1X equivalent, key selection considerations include its 40-pin QFN RoHS package, 3.3 V-only HDA signaling, SPDIF input capability, analog mixer with programmable gain, and Microsoft WLP premium logo compliance for Windows-based platforms.

Technical Context

The 92HD73E2X5NDGXC1X implements Intel HD Audio (HDA) link protocol with full-duplex 7.1-channel support and simultaneous VoIP streaming. Its architecture includes two independent ADC multiplexers (selecting among 12 inputs including CD, ports A–H, and mixer output) and four port input multiplexers routing analog sources to internal signal paths.

Power management follows HDA specification states (D0–D3), with GPIOs, VREF outputs, analog mixer, and input boost remaining active in D1/D2 but disabled in D3. The device uses a 5 V analog supply and 3.3 V digital supply, with all HDA signaling fixed at 3.3 V - unlike the 48QFP variant which supports runtime 1.5/3.3 V selection.

Key Specifications

FAQ

What is the package type and pin count of the 92HD73E2X5NDGXC1X?

The 92HD73E2X5NDGXC1X uses a 40-pin QFN RoHS package with 6 × 6 mm body and exposed thermal pad. This compact footprint is optimized for space-constrained notebook motherboard layouts and differs from the 48QFP variant used in other members of the 92HD73E family. The 92HD73E2X5NDGXC1X pinout is documented in IDT datasheet Figure 13 and Table 24.

Does the 92HD73E2X5NDGXC1X support dual SPDIF outputs?

No, the 92HD73E2X5NDGXC1X supports only a single SPDIF output (pin 39) and one SPDIF input (pin 38). Dual SPDIF output capability is exclusive to the 48QFP package variants (e.g., 92HD73E1X5PRGXC1X), which include dedicated SPDIF_OUT0 and SPDIF_OUT1 pins. The 92HD73E2X5NDGXC1X is functionally limited to one SPDIF transmitter.

What power supplies does the 92HD73E2X5NDGXC1X require?

The 92HD73E2X5NDGXC1X requires a 3.3 V digital supply (DVDD) and a 5 V analog supply (AVDD). Unlike the 48QFP version, it supports only 3.3 V HDA signaling - no runtime 1.5 V option. All I/Os are 3.3 V tolerant, and the device does not support mixed-voltage signaling. Proper decoupling per IDT layout guidelines is required for both rails.

Is the 92HD73E2X5NDGXC1X Microsoft WLP premium logo certified?

Yes, the 92HD73E2X5NDGXC1X meets Microsoft Windows Logo Program (WLP) 3.09 and later premium logo requirements. This certification covers acoustic performance (SNR, THD+N), power state interoperability (D0–D3), jack detection reliability, and driver stability - enabling OEMs to qualify systems for Windows 10/11 premium branding without additional audio validation effort.

Can the 92HD73E2X5NDGXC1X be used with digital microphones?

No, digital microphone inputs (DMIC0/DMIC1) are not supported on the 92HD73E2X5NDGXC1X. These features are exclusive to the 48QFP package variants per IDT datasheet Section 1.3.8 and Table 11. The 40QFN package omits DMIC pins and associated internal circuitry - only analog microphone inputs with programmable 0/10/20/30 dB boost are available on the 92HD73E2X5NDGXC1X.
