Designers pushing the limits in their application can run into situations where the XO performance is inadequate for their next design due to the way it reacts to the noise and ripple in the power supply. To achieve optimal performance, they most likely will find they will need to do more than a simple datasheet evaluation to select their next XO. Read on for details on a PSNR test method to help select an optimal XO.

Since an oscilloscope and phase noise analyzer observe jitter differently, obtaining the same value from both instruments can be challenging. This article presents a phase-noise based methodology that provides similar values as time-interval error jitter derived from an oscilloscope.
