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 ...

When Hackaday runs a contest, we see all manner of clever projects. But inevitably there are some we don’t see, because their builders didn’t manage to get them finished in time. [Park Frazer]’s phase ...

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 ...

But taking a voltage-controlled oscillator at 100 MHz (nominal) and dividing its output by 100 will give you a signal you can lock to a 1 MHz crystal oscillator which is, of course, trivial to build.

IDT has announced a new family of programmable clock generators. These new devices leverage the EEPROM-based programmable platform from previous generations of IDT programmable clocks along with an ...

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 ...

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.

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 ...
