Abstract: Quartz crystals are mechanical resonators with piezoelectric properties. The piezoelectric properties (electric potential across the crystal is proportional to mechanical deformation) allow ...

This tutorial explains the primary design considerations to be addressed in a design of a simple crystal oscillator using AT-cut crystals. The basic qualities of a crystal oscillator and factors that ...

Crystal oscillators exploit the piezoelectric resonance of quartz or alternative piezoelectric materials to generate stable electrical frequencies with high quality factors. Fundamental design ...

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...

Modern technology relies heavily on accurate timing as its fundamental basis, so that items of electronics all have coordinated functions. This applies across a wide range of industry sectors and, ...

Why EMXOs, though less well known than OCXOs, are an appealing alternative for space-system developers. How EMXOs help developers maintain the same level of performance as an OCXO in a smaller, ...

Our hacker [Wil Carver] has sent in his submission for the One Hertz Challenge: Precise Time Ref via 1 Pulse-Per-Second GPS Signal. This GPS Disciplined Oscillator (GPSDO) project uses a Piezo 2940210 ...

Texas Instruments has removed the need for external timing crystals by developing a technique for building high-grade thin film piezoelectric bulk acoustic wave (BAW) resonators within the ...
