Product details
Overview
IDTSTAC9220X5TAEA6XR from IDT is an 8-channel high-definition audio CODEC compliant with Intel HD Audio interface, delivering stereo 24-bit resolution at sample rates up to 192 kHz, 95 dB DAC SNR, and integrated headphone amplifiers for notebook and media-centric desktop PC audio subsystems.
For engineers reviewing the IDTSTAC9220X5TAEA6XR datasheet, IDTSTAC9220X5TAEA6XR pinout, IDTSTAC9220X5TAEA6XR application, or IDTSTAC9220X5TAEA6XR equivalent, key selection considerations include Intel HD Audio interface compatibility, 7.1/5.1 surround support with auxiliary RTC channel, SPDIF I/O, Universal Jacks™ reconfiguration, and dual stereo ADC + four DAC pairs in 48-pin LQFP.
Technical Context
The IDTSTAC9220X5TAEA6XR implements a multi-node High Definition Audio widget architecture per Intel specification, with dedicated AFG (Audio Function Group), DAC0–DAC3, ADC0–ADC1, SPDIFOut, DigIn, and PortA–PortF nodes enabling full jack retasking and dynamic audio path routing. It supports HDA stream-based DMA transfers and unsolicited response handling for real-time jack detection.
Its ΣΔ modulation architecture delivers >95 dB DAC SNR and supports simultaneous 8-channel playback (4× stereo DAC pairs) and 4-channel recording (2× stereo ADCs), with independent volume control, microphone boost (0–40 dB), impedance sensing, and digital PC beep injection across all analog outputs.

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 | 24-bit/96 kHz max sample rate; 90 dB DAC SNR; no SPDIF I/O; 44-pin QFP | Limited to 5.1 audio; lacks S/PDIF and auxiliary RTC channel; lower SNR impacts high-end playback fidelity | Select when cost-sensitive mainstream notebooks require basic HD Audio compliance without premium features |
| VIA VT1708B | 24-bit/192 kHz support; 92 dB DAC SNR; SPDIF Out only (no SPDIF In); 48-pin LQFP | Missing SPDIF input limits digital source flexibility; slightly lower SNR affects critical listening applications | Choose for budget desktops needing 7.1 output and S/PDIF output but not bidirectional digital audio |

FAQ
What interface standard does the IDTSTAC9220X5TAEA6XR use?
The IDTSTAC9220X5TAEA6XR uses the Intel High Definition Audio (HD Audio) interface, a serial link protocol with separate data, clock, and reset signals. It complies fully with Intel's HD Audio specification v1.0a, enabling native driver support in Windows and Linux, and interoperability with Intel PCH audio controllers. The IDTSTAC9220X5TAEA6XR implements all required HDA widgets including AFG, DACs, ADCs, and SPDIF nodes.
Does the IDTSTAC9220X5TAEA6XR support S/PDIF input and output?
Yes, the IDTSTAC9220X5TAEA6XR provides dedicated S/PDIF In and S/PDIF Out pins (Pins 23 and 24), enabling bidirectional digital audio connectivity. This allows direct interfacing with consumer audio equipment such as AV receivers and external DACs, supporting both PCM and compressed Dolby Digital bitstreams. The IDTSTAC9220X5TAEA6XR processes S/PDIF data internally without requiring external logic.
What is the maximum audio resolution and sample rate supported by the IDTSTAC9220X5TAEA6XR?
The IDTSTAC9220X5TAEA6XR supports 24-bit resolution for both ADC and DAC paths, with maximum sample rates up to 192 kHz for playback and recording. This enables high-resolution audio formats including DVD-Audio and studio master files. The IDTSTAC9220X5TAEA6XR maintains this performance across all eight channels in 7.1 mode, verified in datasheet Section 2.2–2.4.
How does Universal Jacks™ functionality work on the IDTSTAC9220X5TAEA6XR?
Universal Jacks™ on the IDTSTAC9220X5TAEA6XR enables runtime reassignment of physical audio jacks via HDA widget configuration-e.g., converting a Line In jack into a Mic In or Headphone Out based on attached device detection. This is implemented through PortA–PortF nodes and ConfigDefault registers (Section 6.13–6.18), allowing OEMs to ship one PCB layout across multiple SKUs. The IDTSTAC9220X5TAEA6XR performs automatic impedance sensing to trigger reconfiguration.
What analog power supply options does the IDTSTAC9220X5TAEA6XR support?
The IDTSTAC9220X5TAEA6XR supports two analog supply voltages: +3.3 V or +5 V AVDD, selectable per system design requirements. Datasheet Sections 2.2–2.4 specify distinct performance characteristics for each supply condition-including SNR, THD+N, and crosstalk-allowing optimization for noise-sensitive or power-constrained platforms. The IDTSTAC9220X5TAEA6XR requires proper decoupling on all AVDD pins (1–4) as defined in the connection diagram.
