Thermometer encoded measure of the FIFO level.
1 = bypasses f
1 = bypasses inverse sinc filter.
1 = bypasses NCO.
0 = default. No gain scaling is applied to the NCO input to
the internal digital modulator.
1 = gain scaling of 0.5 is applied to the NCO input to the
internal digital modulator. This can eliminate saturation
of the modulator output for some combinations of data
inputs and NCO signals.
1 = bypasses phase compensation.
0 = the modulator outputs high-side image.
1 = the modulator outputs low-side image. The image is
spectrally inverted compared to the input data.
1 = ignores Q data from interface and disables the clocks
to Q datapath. Sends I data to both I and Q DACs.
00 = input signal not modulated, filter pass band is from
−0.4 to +0.4 of f
01 = input signal not modulated, filter pass band is from
0.1 to 0.9 of f
10 = input signal modulated by f
0.6 to 1.4 of f
11 = input signal modulated by f
1.1 to 1.9 of f
1 = bypasses first stage interpolation filter.

000000 = input signal not modulated, filter pass band is
from −0.25 to +0.25 of f
001001 = input signal not modulated, filter pass band is
from 0.0 to 0.5 of f
010010 = input signal not modulated, filter pass band is
from 0.25 to 0.75 of f
011011 = input signal not modulated, filter pass band is
from 0.5 to 1.0 of f
100100 = input signal modulated by f
from 0.75 to 1.25 of f
101101 = input signal modulated by f
from 1.0 to 1.5 of f
110110 = input signal modulated by f
from 1.25 to 1.75 of f
111111 = input signal modulated by f
from 1.5 to 2.0 of f
1 = bypasses second stage interpolation filter.
