Description
11
14
Digital Ground
Digital V
CC
Ground pin and power supply pin for the digital portion
of the LM1276. Note the recommended charge
storage and high frequency capacitors, which should
be as close to pins 11 and 14 as possible.
12
SCL
The I2C compatible clock line. A pull-up resistor of
about 2.2 k
should be connected between this pin
and V
CC. A resistor of at least 100 should be
connected in series with the clock line for additional
ESD protection.
13
SDA
The I2C compatible data line. A pull-up resistor of
about 2.2 k
should be connected between this pin
and V
CC. A resistor of at least 100 should be
connected in series with the data line for additional
ESD protection.
15
H Sync
Logic level horizontal sync signal received from the
MCU or sync stripper circuit. This input can also be
derived from the clamp input as long as it is a logic
level signal.
16
17
Digital Ground
Digital V
CC
Ground pin and power supply pin for the digital portion
of the LM1276. Note the recommended charge
storage and high frequency capacitors, which should
be as close to pins 16 and 17 as possible.
18
19
20
DAC 3 Output
DAC 2 Output
DAC 1 Output
DAC outputs for cathode cut-off adjustments and
brightness control. The DAC values are set through
the I2C compatible bus. A resistor of at least 1k
should be connected in series with these outputs for
additional ESD protection.
21
22
Analog Ground
Analog V
CC
Ground pin and power supply pin for the output analog
portion of the LM1276. Note the recommended
charge storage and high frequency capacitors which
should be as close to pins 21 and 22 as possible.
