PhaseLink’s crystal oscillator ICs provide the best level of negative impedance, lowest jitter, and lowest phase noise in the frequency range, up to the 1GHz range. Our best in class buffer outputs (CMOS,LVDS,LVPECL) make them suitable for all types of applications, including low current clock reference, low jitter, low phase noise system clock reference, and small ceramic based SMD crystal oscillators.
