Each DAC channel (V
OUT
L and V
OUT
R) includes a digital attenuation function. The attenuation level can be set
from 0 dB to –63 dB in 0.5-dB steps, and also can be set to infinite attenuation (mute). The attenuation level
change from current value to target value is performed by incrementing or decrementing by one small step size
for every 1/f
S
time interval during 2048/f
S
. The small step size is determined automatically so that it can provide a
transition in attenuation level with a characteristic S-shaped curve from the current value to the target value.
While the attenuation level change sequence is in progress for 2048/f
, processing of the attenuation level
change for any new command is ignored, and the new command is overwritten into command buffer. The last
command for an attenuation level change is performed after present attenuation level change sequence is
finished.
The attenuation data for each channel can be set individually. The attenuation level can be calculated using the
following formula:
Attenuation level (dB) = 0.5
×
(ATx[7:0]
DEC
– 255)
where ATx[7:0]
DEC
= 0 through 255.
For ATx[7:0]
DEC
= 0 through 128, attenuation is set to infinite attenuation.
The preceding table shows attenuation levels for various settings.
