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 ...

In this paper an All Digital phase locked loop is proposed. This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are ...

Related to my search for reduced motor noise (and thanks to all who have made suggestions – ‘scope avaunt this weekend), is a search for speed stability in that motor*. And to someone who is in love ...

The NB4N507A is a fully integrated phase lock loop (PLL) designed to replace expensive crystal oscillators for clock generation in a variety of consumer and networking applications. The IC generates a ...

The real "showstopper" in a standard digital PLL is the interaction between the loops. In a typical design, the Phase Detector and the Frequency Detector run simultaneously.

Some brief theory and typical measurements of phase noise. How to produce the lowest phase noise at a PLL output. A standard design procedure for a typical Type 2, second-order loop. As stated in ...

Whilst poring over 4046 phase locked loop data sheets, I noticed yet another subtle useful difference between the the later faster 74HC4046 (diag from NXP data sheet) and the earlier slower CD4046.
