17. Unless otherwise noted, test conditions are as follows: All zeros input, sample rate = 48 kHz; No load.
18. RESET held HI, all HDA Bus clocks and data lines are running; HDA Interface running with support for
unsolicited responses; All converters are in D3 state.
19. Represents total power for the HDA Bus interface logic playing 6 channels and capturing 4 channels of
48 kHz audio.
20. Full-scale single-ended output signal into a 10 kΩ load.
21. Full-scale differential output signal into a 10 kΩ load.
(The following table demonstrates the total power consumption for typical system operation. These total CODEC
power numbers are derive from the individual block power consumption numbers in the previous table.)
