10-2. PIN DESCRIPTION
PIN 1 80 78 77 PIN NAME XIN XOUT E01 E02 4.5MHz CRYSTAL PHASE COMPARISON OUTPUT PORT If the frequency of the partial oscillation is higher than the basic frequency, these output high, lower than the basic frequency, output low. Otherwise, these are high-z that those frequencies correspond. AM 2 nd CHARGE PUMP OUTPUT PORT. (AM FREQUENCY : 90kHz) CAN BE SUPPLIED UP TO 6.5V DESCRIPTION I/O I O O O

FM VCO INPUT (the signal of the partial oscillation) * INPUT RANGE : 0.07~1.5 Vrms AM VCO INPUT (the signal of the partial oscillation) * INPUT RANGE : 0.07~1.5 Vrms Outputs the pll lock up signal to lock up the pll frequency in high speed. FM IF COUNT INPUT * INPUT RANGE : 10.7MHz + 30kHz, Vpp=0.07~1.5Vrms AM IF COUNT INPUT * INPUT RANGE : 450kHz + 1kHz (AM) : 450kHz + 0.37kHz (LW) * Vpp = 0.07 ~1.5Vrms To check if the memory state is normal on the back-up mode. The application circuit is illustrated on the note of back pages. To check if it is back-up mode(LOW) or normal operation state(HIGH), but it display clock depending on the clock option.
