Clocks are such mundane objects that it’s sometimes hard for them to grab your attention. They’re there when you need them, but they don’t exactly invite you to watch them work. Unless, of course, you ...
Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...
Most electronic clocks, be they analog or digital, use a crystal oscillator (XO) based on a 32.768 kHz crystal for their reference. In fact, it is same crystal that’s commonly used as a real-time ...
Ever wondered how much timing margin your system really has? You’ve probably asked some questions along these lines, such as: Does my crystal really need 20 parts-per-million (ppm) accuracy? What if ...
Digital clock projects have been with us since the 1970s, when affordable LEDs and integrated circuits became available. In 2026 most of them use a microcontroller, but for the AliExpress fans there’s ...
