36. 2 Reference frequency division The reference frequency of 5kHz or 6 25kHz according to the channel step is produced by dividing the reference oscillation 12 8MHz X51 by 2560 or 2048 the data from CPU 1 508 The channel steps of 5kHz 10kHz 15kHz 20 2 25kHz 30kHz and 50kHz use the reference frequency of 5kHz and the channel step of 12 5 2 uses the reference frequency of 6 25kHz 3 Phase comparator The reference frequency of IC53 is 5kHz or 6 25kHz The VCO output frequency divided by N is compared with 5kHz or 6 25kHz in the phase comparator 4 PLL Loop Filter Circuit If the phase error should occur in PLL the charge pump of IC53 Pin13 L band and Pin8 R band outputs the pulse The signal is converted into the DC voltage in PLL loop filter then inputted to the varicap of each VCO unit 5 VVCO Circuit VHF Band Q705 is turned ON and the desired frequency is oscillated in the Colpitts osclllator consisting of Q701 The frequency control voltage is apprled to the varicap D702 D703 and the osciflating frequency is changed then amplified in VCO buffer Q703 and outputted from the VCO unit 6 VVCO Circuit UHF Band Q704 is turned ON and the desired frequency is oscillated in the Colpitts oscillator consisting of Q702 The frequency control voltage is applied to the varicap D704 D705 and the oscillating frequency is changed then amplified in VCO buffer Q703 and outputted from the VCO unit 7 UVCO Circuit
