FUNCTION An input pin for reference clock, tinnect to DOUT (pin 3) of timing LSI (U93N61 ) or DO (pin 3) of timing LSI; following frequencies appear on this pin; At NT3C mode : 9.534964 MHz when CKMD = L level 12.713285 MHz when CKMD = H level At PAL mode : 9.656250 MHz when CKMD = L level 12.875 ~ MHz when CKMD = H level Supply +5 V Wwer. Phase comparator output for input signals RPI (pin 32) and CPI (pin 30). When CPI is advanced, output is Low level. When CPI is delayed, output is High level, When phases are equal, the terminal impedance is High. An input pin for comparison horizontal signal to the phase comparator. Connect to SCHD (pin 33) when comparator is used. Set to L level when comparator is not used. The pulse occurs at the start of lines. Connect to timing LSI. An input pin for the reference horizontal signal to the phase comparator. Connect to HD (pin 31) when comparator is used, Set to L level when comparator is not used. A horizontal synchronization pulse obtained by dividing 4FSC (pin 43). At NTSC mode : dividing into 1 /91 O 4FSC. At PAL mode : dividing into 1/} 135 4FSC ordinarily and dividing into 1/1 137 4FSC during one horizontal period within the V blanking, The pulse occurs at the start of every field. Connect to VDI (pin 2) of timing LSI (LZ93N61 ) or VDI (Pin 1) of timing LSI (U92E62). The pulse is used for detecting field. At NTSC mode : 1st field; LOW 2nd field; HIGH At PAL mode : 1st and 3rd field; LOW 2nd and 4th field; HIGH When the input is High, BCPI (pin 37) and BCP2 (pin 36) are Low.
