Provided By GigiVideo - http://www.digivideo.biz MSM5807 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.
