1.0 ~ 1.2 p. sec. phase jitter (RMS; 12 KHz ~ 20 MHz bandwidth, typical) results from fractional mode technology offers quick-turn quick-turn delivery and low cost. For even lower phase jitter (0.6 ps; integer mode), please evaluate GTQN sereis. XO (Crystal Oscillator) versions are HTQF and HTQN series. Mercury 3GTQF576 series VCXO (Voltage Controlled Crystal Oscillator), 6 Pads SMD 3.3 V CMOS square wave 15 pF load, 10 MHz ~ 250 MHz, 7.0X5.0x1.8 mm.
