Red Video In
Green Video In
Blue Video In
Video inputs. These inputs must be AC
coupled with a 4.7 nF cap. DC restoration is
done at these inputs. A series resistor of
about 33
and external ESD protection
diodes should also be used for ESD
protection.
8
Analog Ground
Ground Pin for the analog circuits of the
LM1269.
9V
CC
Power supply pin for LM1269.
10
V
refRext
Sets the internal current sources through a
10 k
1% external resistor. Resistor value
and accuracy is critical for optimum
operation of the LM1269.
11
SDA
The I
2C data line. A pull-up resistor of about
2k
should be connected between this pin
and +5V. A 300
resistor should be
connected in series with the data line for
protection against arcing.
12
SCL
The I
2C Clock line. A pull-up resistor of
about 2 k
should be connected between
this pin and +5V. A 300
resistor should be
connected in series with the clock line for
protection against arcing.

DAC4
DAC3
DAC2
DAC1
DAC outputs for cathode cut-off adjustments
and brightness control. DAC 4 can be set to
change the outputs of the other three DACs,
acting as the brightness control. The DACs
are set through the I
2C bus.
17
Digital Ground
Ground Pin for the digital circuits of the
LM1269.
