The GTQF, GPQF and GDQF Series are members of Mercury’s Q-Family Quick-Turn crystal oscillators
that can be delivered within days. With low current consumption ( 54 mA for LVPECL 622.080 MHz at 3.3V )
and an integrated phase jitter performance of 1.0 pS RMS, they have gained its precision frequency control
market position by providing engineers with next-day samples for prototypes and low cost, fast delivery
forvolume production. The perfect solution to replace traditional XO’s & VCXO’s that use a more expensive,
highfrequency, fundamental crystal and a noisy PLL multiplier circuit
