What a time to be alive when you can find inexpensive microcontrollers that come with programmable(ish) logic that can operate independently of the system clock. [David Johnson-Davies] recently built ...
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 ...

Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...
One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...
The circuit was constructed to produce a frequency divider with the use of flip flops which are the basic building blocks of sequential logic circuits while forming a T flip-flop configuration. Toggle ...
The master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a ...
Exar has extended its range of telecommunications timing products with a new family of universal clocks. The XR811xx series offers a range of output frequencies from 10MHz to 1.5GHz, with ultra low ...
