IC601 : LC74782-9866 (C, A, B, G models)
On-screen Display Controller
Pin No. Symbol Terminal name
Ground terminal Connection to GND (Digital system ground terminal)
1 VSS1
Crystal oscillation Terminal to connect the crystal of the crystal oscillator for internal synchronous
2 XTAL IN
3 XTAL OUT terminal signal generation and a capacitor or to input an external clock. (2fsc or 4fsc)
Crystal oscillation input Switching terminal between the mode to input a clock externally and the mode
4 CTRL1
switching terminal for crystal oscillation. [L] = Crystal oscillation, [H] = External clock input
Blank output terminal Terminal to output the blank signal (character and bordering OR signal) (MOD0 :
5 BLANK
complex synchronous signal output at [H]). When resetting (RST terminal = [L]),
a crystal oscillation clock is output (but not when resetting by the command).
6 OSC IN LC oscillation terminal Terminal to connect the coil of the oscillator for character output dot clock
generation and a capacitor.
7 OSC OUT
Character output terminal Terminal to output a character signal (MOD0 : It becomes an output terminal to
8 CHARA
judge the external synchronous signal at [H] and outputs the result after judging
existence of the external synchronous signal. When a synchronous signal exists,
[H] is output.) When resetting (RST terminal = [L]), a dot clock (LC oscillation) is
output (but it is not output when reset by the command.)
Enable input terminal Serial data input enable input terminal. The serial data input becomes enable at
9 /CS
[L]. A pull-up resistor is built in (hysteresis input).
Clock input terminal Input terminal of clock for serial data input.
10 SCLK
A pull-up resistor is built in (hysteresis input).
Data input terminal Serial data input terminal. A pull-up resistor is built in (hysteresis input).
11 SIN
Power supply terminal Power supply terminal for complex image signal level adjustment (Power supply
12 VDD2
for analog system)
Video signal output terminal Output terminal for complex image signal.
13 CV OUT
14 NC Connected to GND or unconnected.
Video signal input terminal Input terminal for complex image signal.
15 CV IN
Power supply terminal Power supply terminal (+5V : power supply for digital system)
16 VDD1
Synchronous separation Video signal input terminal of the built-in synchronous separation circuit (When
17 SYN IN
circuit input terminal the built-in synchronous separation circuit is not used, it becomes a horizontal
synchronous signal input or a complex synchronous signal input.)
18 SEP C Synchronous separation Terminal to monitor built-in synchronous separation circuit bias voltage.
circuit bias voltage terminal
Complex synchronous Terminal to output a complex synchronous signal of built-in synchronous
19 SEP OUT
signal output terminal separation circuit ([H] when internally synchronized at MOD1 : [H], [L] output
when externally synchronized) (When the built-in synchronous separation circuit
is not used, SYNIN input signal is output.)
Vertical synchronous Terminal to input a vertical synchronous signal by integrating the output signal of
20 SEP IN
signal input terminal SEPOUT terminal. Connect the integration circuit between SEPOUT terminals.
Fix it to VDD1 when not used.
NTSC/PAL-M switching Pin setting has a priority over switching of NTSC/PAL/PAL-M/PAL-N method.
21 CTRL2
input terminal The NTSC method is selected after [L]= reset.
NTSC/PAL/PAL-M/PAL-N method setting by a command is effective.
[H] = PAL-M method.
SEPIN input control terminal Terminal to control whether or not to input VSYNC signal into SEPIN input
22 CTRL3
terminal. [L] = VSYNC inputted, [H] = VSYNC not inputted.
23 /RST Reset input terminal System reset input terminal. A pull-up resistor is built in (hysteresis input).
24 VDD1 Power supply terminal (+5V) Power supply terminal (+5V : power supply for digital system)
