Function
Modulation mode for second stage interpolation filter
(f
000 = input signal modulated by dc. Filter pass band is
from −0.1 to +0.1 of f
001 = input signal modulated by dc. Filter pass band is
from 0.025 to 0.225 of f
010 = input signal modulated by f
from 0.15 to 0.35 of f
011 = input signal modulated by f
from 0.275 to 0.475 of f
100 = input signal modulated by f
from 0.4 to 0.6 of f
101 = input signal modulated by f
from 0.525 to 0.725 of f
110 = input signal modulated by 3f
from 0.65 to 0.85 of f
111 = input signal modulated by 3f
from 0.775 to 0.975 of f
Second stage interpolation filter bypass.
1 = bypass phase compensation.
Modulation mode for third stage interpolation filter
(f
000 = input signal modulated by dc. Filter pass band is
