"WebbLinear (or analog) PLLs use analog 4-quadrant multipliers, such as mixers, as phase detectors. LPLLs are often used for frequency translation and are therefore found in frequency synthesizers, radios, and phase noise instrumentation. The most common PLL in use today is the classic Digital PLL, so-called due to its use of a digital phase detector. " - Pll phase detector
