 MB8719
MB8719 MB8734 RCI8719 PLL Synthesizer
Overview
This PLL-circuit use a 6 bit (MB8734 and RCI8719) or 7 bit (MB8719) 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.
