• Description: 2 Channel High Definition Audio Codec
• Manufacturer: Realtek Semiconductor Corporation

7.5.
The ALC260(D) 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 ALC260(D), only the audio function (NID=01h) supports 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.

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).

Description
Internal clock is stopped. SDATA-IN and S/PDIF-OUT are floated with
pulled low 47K resistors internally. S/PDIF-IN is also floated. Detection of
‘Link Reset Entry’ and ‘Link Reset Exit’ sequences are supported. All states
are maintained if DVDD is supplied.
Analog block and digital filter are powered down. The data on SDATA-IN is
quiet.
Analog block and digital filter are powered down.
Analog block and digital filter are powered down. The data on SDATA-IN is
quiet.
All headphone drivers are powered down.
All internal mixer widgets are powered down. The DC reference and
VREFOUTx at individual pin complexes are still alive.
All internal references, DC reference, and VREFOUTx at individual pin
complexes are off.
