[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies and since ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

Stable, accurate reference frequencies are basic to almost all digital electronics. The most common references combine quartz crystals with clock-generator circuits, often employing a PLL ...

Crystal oscillators are often one of the last components that a designer thinks about, but the wrong part can quickly kill a design. Moreover, searching through a wide variety of available oscillators ...

We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

Members can download this article in PDF format. Devices ranging from microcontroller units (MCUs) to field-programmable gate arrays (FPGAs) permeate our connected world. To operate properly, such ...
