Phase-locked-loop (PLL) frequency synthesizers are signal sources often employed in many types of electronic equipment. They show up as clock sources in high-frequency instruments and as local ...

Let's continue our discussion of the subsystems in the impedance meter that we've been discussing in the previous posts (see “Related Posts” at the end of page 3). We now move on to the next to last ...

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 ...

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.
