Video signal input
Power supply
Sync separator circuit input
Composite video signal output
Ground connection (analog system ground)
Composite video signal input
Power supply (+5 V: digital system power supply)
Video signal input to the internal sync separator circuit (Used as either the horizontal
synchronizing signal or the composite synchronizing signal input when the internal sync
separator circuit is not used.)

SEPC
Sync separator circuit bias
voltage
Internal sync separator circuit bias voltage monitor

SEPOUT
Composite synchronizing
signal output
Internal sync separator circuit composite synchronizing signal output. Can be switched to
function as a signal (high, low, or ST. pulse) output by the SEL0 and MOD0 setting.
Inputs the vertical synchronizing signal created by integrating the SEPOUT pin output signal.
20
SEPIN
Vertical synchronizing signal input
An integration circuit must be connected to the SEPOUT pin. This pin must be tied to VDD1 if
unused. This pin can be switched to function as the frame signal input mode by setting SEL1
high. This is valid when CTL3 is set high. This input has hysteresis characteristics.
21
CTRL2
NTSC/PAL-M selection input
Pin settings take priority for switching between the NTSC, PAL, PAL-M, PAL-N, NTSC 4.43,
and PAL60 video formats. The NTSC format is selected when this pin is low after a reset.
The command video format (NTSC, PAL, PAL-M, PAL-N, NTSC 4.43, or PAL60) selection is
valid. The PAL-M format is selected when this pin is high.
22
CDLR
Background color phase
adjustment
Background color phase adjustment. Connect a resistor between this pin and ground.
23
RST
Reset input
System reset input.
A pull-up resistor is built in and the input has hysteresis characteristics.
24
VDD1
Power supply (+5 V)
Power supply (+5 V: digital system power supply)
Note: Both VDD1 pins must be connected to the power supply.
