Value Description

ANALOG INTERFACE – Support (9 pins)

CBYPLUMA

11

0.1 µF Reference Bypass Capacitor for LUMA DAC. Connection

point for 0.1 µF Capacitor.

CBYPCHROM

6

0.1 µF

Reference Bypass Capacitor for CHROMA DAC. Connection

point for 0.1 µF Capacitor.

CBYPCOMP

3

0.1 µF Reference Bypass Capacitor for COMPOSITE DAC.

Connection point for 0.1 µF Capacitor.

RREFLUMA

13

1210 Ohm Current Setting Resistor. Connection point for external current

setting resistor for LUMA DAC. The resistor is connected

between RREFLUMA and GND. Output video levels are

inversely proportional to the value of RREF2.

RREFCHROM

8

1210 Ohm Current Setting Resistor. Connection point for external current

setting resistor for CHROMA DAC. The resistor is connected

between RREFCHROM and GND. Output video levels are

inversely proportional to the value of RREFCHROM.

RREFCOMP

99

1210 Ohm Current Setting Resistor. Connection point for external current

setting resistor for COMPOSITE DAC. The resistor is connected

between RREFCOMP and GND. Output video levels are

inversely proportional to the value of RREFCOMP.

VREF

98

1.235 V Voltage Reference Input. External voltage reference input,

internal voltage reference output, nominally 1.235V.
