92HD66C1X3NDGXZBX

Overview

The Tempo Semiconductor 92HD66C1X3NDGXZBX is a six-channel High Definition Audio codec designed for notebook and desktop PC applications. It features two stereo analog-to-digital converters (ADCs) and three digital-to-analog converters (DACs), all operating with 24-bit resolution. The device supports audio sampling rates up to 192 kHz and includes dual capless headphone amplifiers alongside an additional integrated amplifier. It complies with Intel's HD Audio interface specifications, supporting both 1.5V and 3.3V signaling levels. The component operates within a supply voltage range of 3.135 V to 5.25 V and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports full HDA compliance with EuP low power requirements and rapid D3 to D0 resume transitions under 10 milliseconds.
• Integrates dual capless headphone amplifiers and port presence detection capabilities in low power states.
• Includes dual SPDIF outputs for simultaneous HDMI and SPDIF transmission, along with digital microphone inputs.
• Features an integrated AVDD LDO for improved power supply rejection ratio and system-level audio effects.

Applications

• Notebook computer audio subsystems
• Desktop personal computer motherboards
• All-in-one PC audio interfaces

Procurement Notes

Verify the specific package variant required, as the 40-pin QFN version lacks Port E, Mono Out, and GPIO 4 compared to the 48-pin option. Confirm that the ordering suffix aligns with the desired pin count and thermal grade before finalizing procurement orders.

Selection Notes

Select this component when a platform requires six-channel audio processing with high-fidelity output and strict power management constraints. Ensure the design accommodates the necessary analog power supplies and utilizes the TSI HD Sound GUI for optimal configuration of the parametric equalizer and dynamics processing.

Part Context

This part belongs to the 92HD66C series of six-channel HD audio codecs from Tempo Semiconductor. The series provides high-quality audio capabilities for consumer computing devices, offering configurable analog ports and robust power state management to meet modern energy efficiency standards.

Replacement Considerations

Direct substitutes include other members of the 92HD66C family, such as the 92HD66B3X5NLGXZBX, though pinout and feature availability may vary between package types. Verify register compatibility and physical footprint before implementing any cross-series replacement.

FAQ

Does the 40-pin QFN package support Port E?

No, the 40-pin QFN package variant removes Port E, related VREF_Out, Mono Out, and GPIO 4 functionality compared to the 48-pin version.

What is the maximum resume time from D3 to D0 mode?

The codec can resume from D3 to D0 mode with audio activity in less than 10 milliseconds.

Can the device handle simultaneous HDMI and SPDIF output?

Yes, it features dual SPDIF outputs specifically designed to support simultaneous HDMI and SPDIF output for WLP compliance.
