• Manufacturer: Realtek Semiconductor Corporation

7.5.
7.5.1.
The ALC262 does not support Wake-Up events when in low power mode. All power management state
changes in widgets are driven by software. Table 14 shows the System Power State Definitions.
In the ALC262, all the widgets include output/input converters support power control. Software may have
various power states depending on system configuration. Table 15 indicates those nodes that support
power management. To simplify power control, software can configure whole codec power states through
the audio function (NID=01h). Output converters (DACs) and input converters (ADCs) have no
individual power control to supply fine-grained power control.

Power Still Supplied. The codec stops the internal clock. State is maintained.
Definitions
All Power On. Individual DACs and ADCs can be powered up or down as required.
All amplifiers and converters (DACs and ADCs) are powered down. State maintained, analog
reference stays up.
All amplifiers and converters (DACs and ADCs) are powered down. State maintained, but analog
reference off (D1 + analog reference off).
All Power Removed. State lost.
