REC86345 PLL Frequency Synthesizer

Overview

This PLL-circuit use a 8 bit BCD binary programmable divide-by-N counter.

Down-converting of the frequency to the divider

This PLL Circuit use a Mixer and a X-Tal Oscillator to convert the output frequency f _OUT to the f _IN to the PLL Circuit.
The X-Tal frequency is f _XTAL = f _OUT - f _IN



The output frequency can be changed by changing the mixing-xtal or add a new mixing-xtal to the oscillator.
