Silicon Laboratories is offering a new class of oscillator as a frequency reference. The all-silicon Si500 series uses neither a MEMS (microelectromechanical-system) frequency system nor a crystal, ...

[Kerry Wong] recently got himself a frequency counter. Not just any counter, a classic Hewlett-Packard 5350B Microwave Counter. This baby will go 10Hz all the way up to 20GHz with only one input shift ...

I have been experimenting with passive crystal oscillators for over two decades, but while looking around, came across some great articles on active crystal oscillators. Last year I got a few ...

Why EMXOs, though less well known than OCXOs, are an appealing alternative for space-system developers. How EMXOs help developers maintain the same level of performance as an OCXO in a smaller, ...

Like many people who repair stuff, [Learn Electronics Repair] has an oscilloscope. But after using it to test a motherboard crystal oscillator, he started thinking about how people who don’t own 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 ...
