• Full HDA and EuP low power support
• Port presence detect functionality in D3 state
• Dual SPDIF outputs for simultaneous transmission

Applications

• Notebook PC audio systems
• Desktop PC audio platforms
• Microsoft WLP premium logo compliant designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pinout and feature availability. Confirm that the 40-pin package variant matches the required analog port count and GPIO configuration for the target design.

Selection Notes

Select this component when a compact 40-pin solution is required. Note that the 40-pin version omits Port E, Mono Out, and GPIO 4 compared to the 48-pin alternative. Ensure the design accommodates the integrated AVDD LDO for improved PSRR.

Part Context

This part belongs to the 92HD66C series of six-channel HD audio codecs. It shares core architecture with other variants but utilizes a reduced 40-pin QFN package. This package size restricts certain analog ports and GPIO pins available in the larger 48-pin footprint.
