Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...

Sunnyvale, Calif. — Maxim Integrated Products has introduced the DS4M-XO series of crystal oscillators, which supports frequency operation from 100 MHz to 300 MHz and provides frequency margining in a ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...

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.

Historically when hams built low power (QRP) transmitters, they’d use a crystal to set the frequency. Years ago, it was common to find crystals in all sorts of radios, including scanners and handheld ...

Chinese researchers have developed a new type of optical crystal that could help address several major supply chain bottlenecks.

The development of an ammonium fluorooxoborate crystal marks a breakthrough in vacuum ultraviolet laser technology, promising ...

Is the end of the quartz crystal near? Probably not. However, with the availability of new integrated bulk-acoustic-wave (BAW) devices, crystals are going to be replaced in many clock and timing ...
