Logic input pin to select between Bank <A> or <B> of the CV, RGB, or Y/C inputs. Internally pulled high.
Unfiltered analog composite video or luma video input. Internally pulled high. A composite or luma or green
signal must be present on either the CV INF A/Y2 or the CV INF B/Y3 input to provide necessary sync signals
to other channels (R, G, B, Y, C). Otherwise, sync must be provided at SYNCIN. For RGB applications the
green channel with sync can be used as an input to this pin.
Filtered analog composite video or luma video input for Bank <A>. Note that SYNC is stripped from this
signal for the other channels. A composite or luma or green signal must be present on either the CV INF A/Y2
or the CV INF B/Y3 input to provide necessary sync signals to other channels (R, G, B, Y, C). Otherwise, sync
must be provided at SYNCIN. For RGB applications the green channel with sync can be used as an input to
this pin.
Filtered analog composite video or luma video input for Bank <B>. Note that SYNC is stripped from this
signal for the other channels.

Logic input pin to select whether the outputs of CV OUT 1/Y OUT A and CV OUT 2/Y OUT B are from filtered or
unfiltered CV sources. Internally pulled low.
Logic input pin to select whether the outputs of CV OUT 1/Y OUT A and CV OUT 2/Y OUT B are from filtered or
