For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...

Low phase noise oscillators are critical components in modern communication, sensing and radar systems, where extreme frequency stability is paramount. These oscillators offer superior performance by ...

This application note presents the need to use an external Pierce oscillator to replace the RTC oscillator circuit that makes EP93xx susceptible to on-chip noises. It describes the implementation of ...

The evolution of precision clocks. The tradeoffs between MEMS vs. crystal oscillators. The manufacture and cost issues involved. Almost every electronic device you can imagine depends on a precision ...

How do you test the oscillator circuit you just made that runs between 200MHz and 380MHz if all you have is a 100MHz oscilloscope, a few multimeters and a DC power supply? One answer is to put away ...

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.

Just as most electronic products today contain at least one embedded controller, most also have at least one crystal oscillator. In fact, some multiprotocol networking and telecom equipment can ...
