High performance VCXO with 622.08MHz Fundamental Quartz Crystal Resonator

Abstract

This paper presents an overview of a VCXO using 622.08MHz fundamental quartz crystal resonator. The quartz crystal blank has an inverted mesa structure, and has been fabricated by the laminated quartz crystal wafer technology. The characteristics of the VCXO are as follows; the frequency pull range is +/-190ppm(control voltage 1.65+/-1.65V), the phase jitter is 150fs-rms(12kHz to 20MHz), and the package size is 7.0times5.0mm
