1
A/
B
MUX
Logic input pin to select between
Bank <A> or <B> of the CV, RGB,
or Y/C inputs. Internally pulled high.
2
CV
INU
/Y1
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 (see RGB Applications section).
3
CV
INF
A/Y2
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 (see
RGB Applications section).
4
CV
INF
B/Y3
Filtered analog composite video or
luma video input for Bank <B>.
Note that SYNC is stripped from this
signal for the other channels.
