Pin Name and Description
Active Low Reset. Includes a 100kΩ pull - up resistor
Control Pin for SYNC I/O and DATA I/O. Includes a 100kΩ pull - down resistor.
When low or not connected, internal SYNC and DATA are used, pins 9 and 10 are
outputs. When high, supply SYNC and DATA from an external source, pins 9 and
10 are inputs.
Black level capacitor.
White level capacitor.
Input for composite video signal with negative going syncs
Ground 0 volts.
Time constant resistor. Controlling discharge rate of black and white level
capacitor voltages.
