SDM wait-to-settle disable:
1 = at mute, the SDM switches to the mute pattern immediately
0 = at mute, the SDM switches to the mute pattern after settling (can take up to
~45ms)
6
DAC SDM coefficient select (stages 1, 2, 3):
1 = 1/16, 1/2, 1/4
0 = 1/16, 1/4, 1/2
5
DAC SDM local feedback coefficient select: 1 = 1/4096, 0 = 1/2048.
4
DAC SDM local feedback disable: 1 = local feedback disabled, 0 = local feed-
back enabled.
3
DAC Valid Invert: 1 = 7.056MHz valid strobe is inverted, 0 = 7.056MHz valid
strobe is not inverted.
2
DAC Data Invert: 1 = 1-bit outputs are inverted, 0 = 1-bit outputs are not invert-
ed.
1
Disable built-in -6dB digital attenuation: 1 = -6dB disabled, 0 = -6dB enabled.
0
DAC Gain Fade Enable:
1 = gain will be slowly faded from old value to new value (~10ms)
0 = gain will jump immediately to new value.
