Functions
GND pin (digital grounding)
Oscillation pins for connecting a crystal oscillator and capacitor to generate internal
synchronous signals
Test output pin
System reset input pin
Clock input pin for serial data input
Serial data input pin. Serial 16-bit data input is supported
Enable input pin for serial data input. If this pin becomes active (active low), the serial data
input is enabled
Level input pin for adjusting blank levels
Level input pin for adjusting character levels
Power supply pin for adjusting composite video signal levels (analog power supply)
Output pin for composite video signal
GND pin (analog grounding)
Input pin for composite video signal
Supply voltage pin (+5V)
Input pin for synchronous signal separation circuit
Adjustment pin for synchronous signal separation circuit (A capacitor is connected to this
pin)
Composite synchronous signal output pin for synchronous signal separation circuit
Vertical synchronous signal input pin. The input signal to this pin is generated by
integrating the output signal from the SEPOUT pin. Add an integral circuit between the
SEPOUT pin and the SEPIN pin
Oscillation pins for connecting a coil and capacitor to generate character output dot clocks
Supply voltage (+5V)
