The ability to sustain oscillation for a given quartz crystal oscillator design depends heavily on the crystal’s motional parameters, board parasitics and oscillator circuit characteristics. The oscillator circuit is a closed loop system that sustains oscillation at an operating frequency depending on the crystal parameters including, crystal plating capacitance (CL), crystal equivalent series resistance (ESR), external loading capacitors, trace parasitics and the oscillator amplifier’s gain & phase response.

 

The PAS test service provides a direct measurement of all variables associated with the quartz crystal oscillation.
