Input Multiplexers
92HD73E implements 4 port input multiplexers. These multiplexers allow a preselection of one of
four possible inputs:
ADC Multiplexers
92HD73E implements 2 ADC input multiplexers. These multiplexers incorporate the ADC record
gain function (0 to +22.5dB gain in 1.5dB steps) as an output amp and allow a preselection of one of
12 possible inputs:

Power Management
The HD Audio specification defines power states, power state widgets, and power state verbs.
Power management is implemented at several levels. The Audio Function Group (AFG) and all con-
verter widgets support the power state verb F05/705 (as well as the pin widget associated with pin
47.) Converter widgets are active in D0 and inactive in D1-D3.
The following table describes what functionality is active in each power state supported by the AFG.
