Stable, accurate reference frequencies are basic to almost all digital electronics. The most common references combine quartz crystals with clock-generator circuits, often employing a PLL ...

The overtone version of a Pierce oscillator, with extra tuned circuit. Fairchild Semiconductor app note 340, HCMOS Crystal Oscillators. Putting an overtone crystal in the Pierce circuit shown above ...

Fig 1. One of the most popular crystal oscillator types is the inverter crystal drive circuit. Fig 2. Shown is the crystal reactance of the third-overtone XO’s third tone. Fig 3. Analog multiplier ...

Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...

Heralded as the industry's first crystal oscillator for PCI Express applications with a high-speed, current-steering logic (HCSL) output, the DS4100H eliminates the need to translate from CMOS, LVDS, ...
