92HD66B1X3NDGXZBX

Overview

The Tempo Semiconductor 92HD66B1X3NDGXZBX is a four-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), supporting 24-bit resolution and sample rates up to 192 kHz. The device includes dual capless headphone amplifiers and operates with a 3.3V digital supply and a 3.3V analog supply, utilizing 1.5V HDA signaling. It is housed in a 40-pin QFN package.

Feature Summary

Supports full HD Audio interface compliance including EuP low power modes
Integrates dual capless headphone amplifiers for simplified board design
Features dual SPDIF outputs enabling simultaneous HDMI and SPDIF transmission
Includes integrated AVDD LDO to improve power supply rejection ratio

Applications

Notebook computer audio systems
Desktop PC motherboard integration
Home entertainment system connectivity

Procurement Notes

Verify the specific silicon stepping revision indicated by the suffix before procurement. Confirm that the 3.3V analog supply requirement aligns with the target platform's power architecture. Ensure the 40-pin QFN footprint matches the PCB layout specifications exactly.

Selection Notes

Select this component when a 3.3V analog supply is available instead of a 5V rail. Choose this part over the X5 variants if the design requires lower analog voltage operation. Verify that the 40-pin package constraints meet the spatial requirements of the enclosure.

Part Context

This model belongs to the 92HD66B family of four-channel HD Audio codecs. It shares core functionality with other variants but is distinguished by its specific analog voltage support and packaging configuration. The 'X3' designation indicates compatibility with a 3.3V analog supply domain.

Replacement Considerations

Direct substitutes include other 92HD66B series parts with matching pinouts. Verify that alternative packages or voltage variants do not require schematic modifications.
