5 / 21 page Pin Functions Pin No. Symbol Function Description 1VSS Ground Ground connection 2XtalIN1 Crystal oscillator connection Connection for the crystal and capacitor used to form the crystal oscillator that generates 3XtalOUT1 the internal synchronization signal. The oscillator can be selected with a command switch. 4 HSYNCOUT Horizontal synchronization Outputs the horizontal synchronization signal (AFC). The output polarity can be selected output (metal option). Also functions as general output port (command switch). 5XtalIN2 Crystal oscillator connection Connection for the crystal and capacitor used to form the crystal oscillator that generates 6XtalOUT2 the internal synchronization signal. 7 VSYNCOUT Vertical synchronization output Outputs the vertical synchronization signal. The output polarity can be selected (metal option). Also functions as general output port (command switch). 8CS Enable input Enables/disables serial data input. Serial data is enabled when this pin is low (hysteresis input). Pull-up resistor built in (metal option). 9 SIN Data input Serial data input (hysteresis input). Pull-up resistor built in (metal option). 10 SCLK Clock input Clock input for serial data input (hysteresis input). Pull-up resistor built in (metal option). SECAM mode switch input/ During input, switches between SECAM and other modes. 11 SECAM output (command switch) During output, functions as general output port or internal V output (command switch). Low = other modes, high = SECAM mode 525/625 switch input/output During input, switches between 525 scan lines and 625 scan lines. 12 525/625 (command switch) During output, functions as general output port or character data output (command switch). Low = 525 lines, high = 625 lines NTSC/PAL switch input/output Switches the color mode between NTSC and PAL. 13 NTSC/PAL (command switch) During output, functions as general output port or frame data output (command switch). Low = NTSC, high = PAL Switch FSC between 3.58 MHz and 4.43 MHz. 14 3.58/4.43 3.58/4.43 switch input/output During output, functions as general output port or half-tone output (command switch). (command switch) Low = 3.58, high = 4.43 15 RST Reset input System reset input pin, low is active (hysteresis input). Pull-up resistor built in (metal option). 16 CVOUT Video signal output Composite video output 17 VDD2 Power supply connection Power supply connection for composite video signal level generation 18 CVIN Video signal input Composite video input 19 CVCR Video signal input SECAM chroma signal input 20 SYNCIN Sync separator circuit input Built-in sync separator circuit video signal input 21 SEPC Sync separator circuit Built-in sync separator circuit 22 VSS Ground Ground connection 23 PDOUT Control voltage output AFC control voltage output 24 AMPIN AFC filter connection Filter connection 25 AMPOUT 26 FC Control voltage input AFC control voltage input 27 VCOIN LC oscillator connection VCO LC oscillator circuit coil and capacitor connection 28 VCOOUT External synchronization signal Outputs the exclusive NOR of the horizontal synchronization signal (AFC) and CSYNC (sync 29 SYNCDET detection output separator). The output polarity can be selected (metal option). Also functions as general output port (command switch). 30 VDD1 Power supply connection Power supply connection (+5 V: digital system power supply) No. 4846-5/21 LC74761, LC74761M |
