92HD66B3X3NLGXZBX

Overview

The 92HD66B3X3NLGXZBX is a four-channel High Definition Audio codec from Tempo Semiconductor, designed for notebook and desktop PC applications. It features two stereo ADCs and supports 24-bit resolution with sample rates up to 192 kHz. The device includes dual capless headphone amplifiers and operates with a 3.3V digital supply and a 5V analog supply. It utilizes a 48-pin QFN package and supports switchable 1.5V or 3.3V HDA signaling levels.

Feature Summary

Dual capless headphone amplifier integration
Full HD Audio interface compatibility
Low power management with D3 transitions
Support for simultaneous HDMI and SPDIF output

Applications

Notebook PC audio systems
Desktop PC audio systems
Home entertainment system connectivity

Procurement Notes

Verify the specific silicon stepping revision by contacting the manufacturer, as indicated by the 'yy' suffix in the ordering information. Confirm that the design requires the 48-pin QFN package variant which supports switchable HDA signaling levels. Ensure the application board provides the necessary 3.3V digital and 5V analog power supplies for proper operation.

Selection Notes

Select this component when a 48-pin footprint is required for designs needing switchable HDA signaling voltages. It is suitable for platforms requiring dual capless headphone outputs and simultaneous digital audio transmission via SPDIF. Verify that the commercial temperature range meets the environmental requirements of the target device.

Part Context

This part belongs to the 92HD66B series of low-power, high-fidelity audio codecs. It is specifically the industrial/commercial temperature variant housed in a 48-pin QFN package. The '3' in the model number denotes the switchable HDA signaling capability, distinguishing it from fixed voltage variants.

Replacement Considerations

Direct replacements within the same family include other 92HD66B variants with different pin counts or signaling options, such as the 40-pin versions. Cross-family replacement with other Tempo Semiconductor codecs may require schematic and software driver modifications.
