Optical Phase-Locked Loop Technologies in Communication Systems

Optical phase-locked loops (OPLLs) are closed-loop control systems that stabilise and synchronise the phase of a slave laser with respect to a reference source, enabling coherent optical generation ...

Phase-locked loop triumph

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 – ...

Unlock The Phase Locked Loop

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 ...

Fully Digital Implemented Phase Locked Loop

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 ...

Low Power Phase-Locked Loop with VCO

The 74HC/HCT4046A are phase-locked loop (PLL) with linear voltage-controlled oscillator (VCO) CMOS device having pins suited to 4046 in a 4000B series. These devices comply to JEDEC standard no. 7A.

A tiny useful discovery about the 4046 phase locked loop chip

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.
