Equivalent & Alternatives
The following parts are listed as comparable options for similar HD Audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ALC269VC | Realtek codec with 2-channel DAC/ADC, no dual S/PDIF, lower THD+N (0.02% vs. 0.01%), no Dolby-certified firmware stack. | Limited to stereo playback/recording; lacks WLP 3/4 premium compliance and integrated Dolby technologies. | Select when cost sensitivity outweighs 5.1 audio, dual S/PDIF, or branded audio feature requirements. |
| 92HD87B1X5PRGXB2X | IDT successor with enhanced 7.1 channel support, higher integration (integrated jack-detect comparators), and updated SKPI framework. | Requires updated driver stack; supports more complex port topologies but increases BOM count for legacy designs. | Select for new designs targeting next-gen WLP 4.x compliance and expanded multi-mic array support. |
Compared with ALC269VC and 92HD87B1X5PRGXB2X, the 92HD73C1X5PRGXB2X uniquely balances WLP 3/4 premium certification, dual S/PDIF output, and factory-integrated Dolby technologies - making it optimal for mid-tier notebooks requiring certified audio performance without full 7.1 channel complexity.

FAQ
What audio interface standard does the 92HD73C1X5PRGXB2X implement?
The 92HD73C1X5PRGXB2X implements Intel's High Definition Audio (HD Audio) Interface specification, fully compliant with the AC'97 successor architecture. It uses a serial bit-stream interface with time-division multiplexed data lanes, supporting up to 15 bidirectional streams. The 92HD73C1X5PRGXB2X also meets Microsoft WLP 3/4 premium logo requirements, ensuring guaranteed Windows driver compatibility and certification readiness for OEMs shipping Windows-based systems.
Does the 92HD73C1X5PRGXB2X support digital microphones?
Yes, the 92HD73C1X5PRGXB2X natively supports digital microphones in mono, stereo, or quad configurations via its DMic0 and DMic1 nodes. It accepts PDM input directly and performs on-chip decimation and format conversion to PCM. This eliminates external PDM-to-I²S bridges and reduces BOM count and PCB area. The 92HD73C1X5PRGXB2X also provides four programmable VREF outputs to bias electret or MEMS mics, making it suitable for advanced voice capture in laptops and conferencing devices.
What is the maximum supported sample rate and resolution for the 92HD73C1X5PRGXB2X?
The 92HD73C1X5PRGXB2X supports stereo audio at up to 192 kHz with 24-bit resolution on both DAC and ADC paths. This capability applies to all three stereo DACs and two stereo ADCs. The 92HD73C1X5PRGXB2X maintains this performance across its full analog supply range (+3.3 V to +5 V) and meets THD+N specifications (<0.01%) at 1 kHz, 0 dBFS, confirming suitability for high-resolution consumer and prosumer audio applications.
How many analog audio ports does the 92HD73C1X5PRGXB2X provide, and what detection features do they include?
The 92HD73C1X5PRGXB2X provides nine stereo analog ports (Port A through Port I), each configurable as line-in, mic-in, headset-out, or speaker-out. All ports include hardware-assisted jack presence detection with interrupt capability, enabling immediate OS-level notification of plug/unplug events. Presence sensing is implemented via integrated comparators and GPIO-controlled biasing, allowing robust detection even with non-standard jack wiring or high-impedance accessories - a critical feature for reliable hot-plug audio in modern notebooks.
Is the 92HD73C1X5PRGXB2X pin-compatible with other IDT HD Audio codecs like the 92HD75B or 92HD87 series?
No, the 92HD73C1X5PRGXB2X is not pin-compatible with the 92HD75B or 92HD87 series. While all belong to IDT's HD Audio family and share functional similarities, the 92HD73C1X5PRGXB2X uses a 48-pin QFP package with a unique pin assignment optimized for its 9-port analog I/O and dual S/PDIF layout. The 92HD75B uses a different pinout and package variant, and the 92HD87 series introduces additional GPIOs and jack-detect logic that require PCB redesign. Migration requires schematic and layout revision - the 92HD73C1X5PRGXB2X must be treated as a distinct footprint.
