PIN DESCRIPTION
PIN NAME
1 A/B MUX
2 CVINU/Y1
3 CVINFA/Y2
4 CVINFB/Y3
5 GND
6 VCC
7 RINA/Y4
8 RINB / Y5
9 GINA/Y6
10 GINB/Y7
11 BINA/C1
FUNCTION
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 CVINFA/Y2 or the CVINFB/
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).
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
CVINFA/Y2 or the CVINFB/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).
Filtered analog composite video or
luma video input for Bank <B>.
Note that SYNC is stripped from this
signal for the other channels.

FUNCTION
12 BINB/C2
Filtered analog BLUE video or
chroma video input for Bank <B>
13 SWAP CVF
Logic input pin to select whether
the outputs of CVOUT1/YOUTA and
CVOUT2/YOUTB are from filtered or
unfiltered CV sources. See Table 1.
Internally pulled low.
14 SWAP CVU
Logic input pin to select whether
the outputs of CVOUT1/YOUTA and
CVOUT2/YOUTB are from filtered or
unfiltered CV sources. See Table 1.
Internally pulled low.
15 BOUT/COUT
16 GOUT/YOUTD
17 VCCORGB
Analog BLUE video output or
chroma output from either BINA/C1
or BINB/C2
Analog GREEN video output or
luma output from either GINA/Y6 or
GINB/Y7
5V power supply for output buffers
of the RGB drivers
18 ROUT/YOUTC
Analog RED video output or luma
output from either RINA/Y4 or RINB/
Y5
19 GNDO
Ground for output buffers
20 CVOUT2/YOUTB Composite video output for channel
2 or luma output.
21 CVOUT1/YOUTA Composite video output for channel
1 or luma output.
22 VCCOCV

of the CV drivers.
23 SYNCIN
Input for an external H-sync logic
signal for filtered channels. TTL or
CMOS. For normal operation
SYNCOUT is connected to
SYNCIN.
24 SYNCOUT
Logic output for H-sync detect for
CVINFA/Y2 or CVINFB/Y3. TTL or
CMOS. For normal operation
SYNCOUT is connected to
SYNCIN.
