92HD66C2X3NDGXZBX

Overview

The Tempo Semiconductor 92HD66C2X3NDGXZBX 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 at sampling rates up to 192 kHz. The device integrates dual capless headphone amplifiers and supports Intel HD Audio Interface standards, including full EuP low power compliance. It operates within an extended temperature range of -40°C to +85°C and utilizes a 48-pin QFN package.

Feature Summary

• Supports simultaneous HDMI and SPDIF output via dual SPDIF outputs for WLP compliant systems
• Integrates high-performance analog mixer and 12-band fully parametric equalizer
• Enables dynamic stream switching to improve multi-streaming user experience
• Provides port presence detection in D3 power state with or without bit clock

Applications

• Notebook PC audio subsystems
• Desktop PC motherboard integration
• High Definition Audio interface implementations

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm pinout compatibility and package type. Confirm that the component meets required environmental specifications for the target application. Ensure that the manufacturer documentation is consulted for accurate RoHS compliance details before finalizing procurement orders.

Selection Notes

Select this model when a 48-pin QFN package is required for expanded port functionality compared to the 40-pin variant. Verify system requirements for dual capless headphone amplifier support and integrated AVDD LDO for improved PSRR. Ensure the design accommodates the specified operating voltage ranges and thermal characteristics.

Part Context

This component belongs to the 92HD66C series of six-channel HD audio codecs from Tempo Semiconductor. The series includes variants with different pin counts and feature sets, such as the 40-pin version which lacks Port E and Mono Out capabilities. The 92HD66C2X3NDGXZBX specifically denotes the 48-pin configuration with extended industrial temperature ratings.

Replacement Considerations

The 92HD66C1X3NDGIZBX serves as a functional alternative but utilizes a 40-pin QFN package, resulting in reduced analog port availability.
