3DYC Signal Quality Gain [7:0]
When the input signal quality is not good, for example weak broadcast signals or poor VCR signals, 3DCY
comb filtering is automatically turned off. This register sets the gain, or sensitivity, to distinguish poor signal
quality. A smaller value in this register favors application of 3DYC, whereas a larger value favors 2DYC.

3DYC Signal Quality Coring [15:8]
When the input signal quality is not good, for example weak broadcast signals or poor VCR signals, 3DCY
comb filtering is automatically turned off. This register sets the coring value used to distinguish poor signal
quality. A larger value in this register favors application of 3DYC, whereas a smaller value favors 2DYC.

Comp:
0 = Crosstalk compensation only. Use if SAW IF stage used.
1 = Crosstalk and low-frequency gain compensation. Use if non-SAW IF stage used.
U: Enable high frequency U gain
0 = Enabled
1 = Disabled
V: Enable high frequency V gain
0 = Enabled
1 = Disabled
IF enable:
0 = IF compensation disabled (default)
1 = IF compensation enabled
