Power Management
Each group of echo cancellers can be placed in Power Down mode by writing a “0” into the PWUP bit in their
respective Main Control Register. When a given group is in Power Down mode, the corresponding PCM data are
bypassed from Rin to Rout and from Sin to Sout with two frames delay. Refer to the Main Control Register section
for description.
The typical power consumption can be calculated with the following equation:
P
C
= 9 * Nb_of_groups + 3.6, in mW
where 0

Call Initialization
To ensure fast initial convergence on a new call, it is important to clear the Adaptive filter. This is done by putting the
echo canceller in bypass mode for at least one frame (125
μ
s) and then enabling adaptation.
