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 ...

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 ...

I have always had a soft spot for phase-locked loops – at least, I have since I first found out what they were. What I like about them is that they servo into the best answer for a given situation – ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...

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.

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 ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low ...

That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...
