The frequency counter in Figure 4 was configured with a one second gate time, during which the irregular pulse train was be smoothed. It used the same 10 MHz crystal oscillator as the divider chain ...

This project originated from the need to produce a linear crystal-controlled ramp signal for an HP 8620C RF sweep oscillator. It is inspired by a previously published ramp generator design [1]. That ...

It is one of our favorite chips, and the brains behind the Arduino UNO and its clones, and it’s getting a tweak (PDF). The ATmega328 and other megaX8-series chips have undergone a subtle desi… ...

Micrel’s MX55/57 FUSION crystal oscillator clocks push phase jitter down to 170 fs rms (12 kHz to 20 MHz). With an eye toward advanced communications, the oscillators handle frequencies ranging ...
