System Design of 100MHz New Frequency Standard with an Excellent Behavior

摘要

The purpose of this paper is to analyze a system which uses a passive quartz resonator as its frequency reference , an assemble system design approach has been proposed which uses both phase-lock and frequency-lock techniques to obtain an optimum transferring of frequency stability of the reference signal by selecting the optimal bandwidth. The phase noise of l00MHz assemble system output can be below -120dB / Hz near carrier l0Hz, the corresponding frequency stability for sample time over one second can be finally improved to sigma(sub y)(Tau)2 approximately 3 * 10(exp 13)(tau >= 1s). Theoretical analysis and system design on 5MHz frequency-lock loop and l00MHz phase-lock loop have been proposed in this paper, some experimental results have also been given.
