32 Oversampling
The OVER bit is used to control the oversampling rate of the delta-sigma D/A converters.
Setting OVER = 1 might improve out-of-band noise characteristics in some application environments, but it might
also slightly affect baseband performance.
Writing over this bit during normal operation may generate pop noise.
DREV2: Output Phase Select (DAC)
Default value: 0
DREV2 = 0
DREV2 = 1
Normal output (default)
Inverted output
The DREV2 bit is used to control the phase of the analog signal outputs (V

L and V

R).
MUT2x: Soft Mute Control (DAC)
where x = 1 or 2, corresponding to the DAC output V

L (x = 1) and V
OUT
R (x = 2).
Default value: 0
MUT2x = 0
MUT2x = 1
Mute disabled (default)
Mute enabled
The mute bits, MUT21 and MUT22, are used to enable or disable the soft mute function for the corresponding
DAC outputs, V
OUT
L and V
OUT
R. The soft mute function is incorporated into the digital attenuators. When mute is
disabled (MUT2x = 0), the attenuator and DAC operate normally. When mute is enabled by setting MUT2x = 1,
the digital attenuator for the corresponding output is decreased from the current setting to infinite attenuation at
the rate of one 0.5-dB step for every 8/f
S
time interval. By setting MUT2x = 0, the attenuator is increased to the
previously programmed attenuation level at the rate of one 0.5-dB step for every 8/f
S
time interval. This provides
pop-free muting of the DAC output.
