The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...

A novel fast locking Digital Phase-Locked Loop (DPLL) has been proposed with simple control unit to improve locking time. A Frequency Difference Stage (FDS) is added to produce a 3-bit code represents ...

This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...

Some brief theory and typical measurements of phase noise. Standard analysis of PLL phase noise used by most CAD applications. How to produce the lowest phase noise at a PLL output. A standard design ...

Abstract: In this study, we present a digital phase-locked-loop (DPLL) specifically designed for enhancing the performance of optical frequency transfer over long-distance communication fiber link. By ...
