XtalOUT
connection
the internal synchronizing signal. Also used for an external clock input. (2fsc: 7.159 MHz)
4
CTRL1
Crystal oscillator input
Switches between the external 2fsc clock input mode and the crystal resonator driving mode.
switching
Low: crystal oscillator, high: external clock input
5
CSYNOUT
Composite synchronizing
Outputs the composite synchronizing signal. Outputs the crystal oscillator clock on a reset due
signal output
to a low level on the RST pin. Does not output any signal on a command reset.
6
OSCIN
LC oscillator
Connections for the coil and capacitor that form the oscillator that generates the character
7
OSCOUT
output dot clock.
External synchronizing signal
Outputs the judgment as to whether or not an external synchronizing signal is present. Outputs
8
SYNCJDG
state judgment output
a high level when a synchronizing signal is present. Outputs the dot clock (LC oscillator) on a
reset due to a low level on the RST pin. Does not output any signal on a command reset.
9CS
Enable input
Enable input for serial data input. Serial data input is enabled by a low level. A pull-up resistor is
built in. (This input has hysteresis characteristics.)
10
SCLK
Clock input
Serial data input clock input. A pull-up resistor is built in. (This input has hysteresis characteristics.)
11
SIN
Data input
Serial data input. A pull-up resistor is built in. (This input has hysteresis characteristics.)

20
CTRL2
NTSC/PAL-M switching input
Switches the synchronizing signal generator between NTSC and PAL-M formats. Low: NTSC,
high: PAL-M
21
CVOUT
Composite video signal output
Outputs a composite video signal.
22
NC
This pin must be level open or connected to ground.
23
CVIN
Composite video signal input
Inputs a composite video signal.
24
CTRL3
SEPIN input control
Controls whether the VSYNC signal is input to the SEPIN input. Low: VSYNC is input,
high: VSYNC is not input.
25
SYNIN
Sync separator circuit input
Video signal input to the built-in sync separator circuit. (Input either a horizontal or composite
synchronizing signal to this pin if the built-in sync separator circuit is not used.)
26
SEPC
Sync separator circuit
Adjusts the built-in sync separator circuit. (Connect a capacitor to this pin.)

(Leave this pin open if the built-in sync separator circuit is not used.)
27
SEPOUT
Composite synchronizing
Outputs the built-in sync separator circuit composite synchronizing signal.
signal output
(Outputs the SYNIN input signal if the built-in sync separator circuit is not used.)
Vertical synchronizing
Integrates the SEPOUT output signal and inputs a vertical synchronizing signal.
28
SEPIN
signal input
An integration circuit must be connected between this pin and the SEPOUT pin. This pin must
be tied to VDD1 if it is not used.
29
RST
Reset input
The system reset input. A pull-up resistor is built in. (This input has hysteresis characteristics.)
