Description
1VSS
Ground
Ground connection
2
XtalIN1
Crystal oscillator connection
Connection for the crystal and capacitor used to form the crystal oscillator that generates
3
XtalOUT1
the internal synchronization signal. (For an NTSC crystal oscillator 4fsc = 14.318 MHz.)
4
HSYNCOUT
Horizontal synchronization
Outputs the horizontal synchronization signal (AFC). The polarity can be selected with a
output
metal switch.
5
XtalIN2
Crystal oscillator connection
Connection for the crystal and capacitor used to form the crystal oscillator that generates
6
XtalOUT2
the internal synchronization signal. (For a PAL crystal oscillator 4fsc = 17.734 MHz.)
7
VSYNCOUT
Vertical synchronization output
Outputs the vertical synchronization signal. The polarity can be selected with a metal switch.
8CS
Enable input
Enables/disables serial data input. Serial data is enabled when this pin is low. Pull-up
resistor built in (hysteresis input).
9
SIN
Data input
Serial data input. Pull-up resistor built in (hysteresis input).
10
SCLK
Clock input
Clock input for serial data input. Pull-up resistor built in (hysteresis input).
11
SECAM
SECAM mode switch input
Switches between SECAM and other modes.
Low = other modes, high = SECAM mode
12
525/625
525/625 switch input
Switches between 525 scan lines and 625 scan lines.
Low = 525 lines, high = 625 lines
13
NTSC/PAL
NTSC/PAL switch input
Switches the color mode between NTSC and PAL.
Low = NTSC, high = PAL
14
3.58/4.43
3.58/4.43 switch input
Switch FSC between 3.58 MHz and 4.43 MHz.
Low = 3.58, high = 4.43
15
RST
Reset input
System reset input pin, low is active (reset).
Pull-up resistor built in (hysteresis input).
