Clock Oscillator in mini package – Clock in a Can
https://www.electronics-lab.com/clock-oscillator-mini-package-clock-can/
Most microcontroller implementation these days, use the traditional capacitor + crystal approach to generate their clock, this approach sometimes, however, lead to problems, especially when used in prototyping situations with a breadboard, jumper wires, etc., all of which have an (unknown) inherent capacitance that could lead to the clean 8 or 16MHz signal we desire, […]
The top 10 crystal oscillators from SnapEDA
https://www.electronics-lab.com/top-10-crystal-oscillators-snapeda/
Elizabeth Bustamante @ snapeda.com lists the top 10 crystal oscillators used today. She writes: A crystal oscillator is an electronic circuit that generates an electrical signal with a very precise frequency. To achieve this, it uses the mechanical resonance of a vibrating crystal made of piezoelectric material. The first crystal oscillator was invented in the […]
CH340E, A New Small Serial to USB Chip
https://www.electronics-lab.com/ch340e-new-small-serial-usb-chip/
WCH, a Chinese integrated circuits manufacturer, has just released a new serial to USB chip called CH340E. Unlike other CH340 chips, it doesn’t require an external crystal and also needs less PCB space and BOM. CH340 is a 3x3mm tiny chip comes in MSOP10 package and has 10 pins. Although it is smaller than other alternatives, it is […]
Simple crystal tester
https://www.electronics-lab.com/simple-crystal-tester-3/
Dilshan Jayakody build a simple crystal tester based on Colpitts oscillator. He writes: This is simple Colpitts oscillator to test commonly available passive crystals which range between 2MHz to 27MHz. This unit must connect to an oscilloscope and/or frequency counter to get the frequency of the crystal. This circuit is design to work around 9V […]

E. Schrama @ ejo60.wordpress.com uses an Arduino and a DCF77 time signal receiver to test the stability of an ovenized crystal oscillator running at 1 MHz. In this experiment I will use an Arduino and a DCF77 time signal radio receiver to measure the stability of an ovenized crystal oscillator running at 1 MHz. It […]
