... The basic phase-lock-loop (PLL) configuration using an ex- ternal prescaler consists of a high-stability crystal reference oscillator, a prescaler such as the National Semiconductor LMX5080, a low frequency synthesizer, a voltage controlled oscillator (VCO), and a loop filter. The frequency synthesizer typically includes programmable reference [R] and feedback [N] frequency dividers, a phase detector, as well as a charge pump ...
