Abstract :
This article reports a digital frequency synthesizer using adaptive mode-coupled resonator VCSO (voltage controlled SAW oscillator) circuit for low cost, low phase noise, and low jitter applications. The typical measured phase noise @ 10 kHz offset from the 1 GHz carrier is -152dBc/ Hz, with RMS jitter less than 6 femto-seconds.
