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 ...

In the previous segment of this article series, we discussed in detail the operation of a crystal oscillator. We’ll now extend the discussion to various parameters associated with crystal oscillators ...

Oscillators may use crystals as precise tuned circuits. If you have a vector network analyzer (VNA) — or even some basic test equipment — you can use it to learn the parameters of a crystal. [All ...

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 ...

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 ...

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 ...
