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 ...

It is often necessary for designers to implement a digital clock divider where the output frequency is not an integer factor of the reference clock. Today's newer FPGA technologies usually contain ...

Most of us know that a quartz clock uses a higher frequency crystal oscillator and a chain of divider circuits to generate a 1 Hz pulse train. It’s usual to have a 32.768 kHz crystal and a 15-stage ...

This reference design features the 8T49NS010 integrated circuit that functions as a clock synthesizer with a built-in fanout buffer and divider. By using an external clock source or a crystal, the ...

Spacecraft timing systems must provide highly stable, precise signals for navigation, communications and scientific instruments, even when GNSS signals are weak or unavailable. Designers frequently ...

Clock-distribution devices create multiple copies of a master clock and distribute them to a variety of integrated circuits. They accept single-ended or differential clock inputs and supply multiple ...

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 ...
