3rd OT vs SAW Oscillator Performance - Comparison of a 3rd Overtone oscillator design and a SAW (Surface Acoustic Wave) resonator design.
The differences in phase noise and temperature characteristics of these two technologies used to obtain high frequency references are covered.
Determining Peak to Peak Frequency Jitter - Given RMS Jitter, how is Peak to Peak Jitter determined.
FD5 and FD7 Application Article - The article was written by Doctor Lin Wu of TI about the CDCE949 clock generator. This is the semiconductor device that operates the Pletronics FD5 and FD7 clock oscillators.
Pletronics Catalog - This obsolete Pletronics catalog of devices is being provided to help in obtaining details of older and obsolete devices. The device specifications and information is not current.
Last printed in late 2004.
