Features
The (V)MQF___T , (V)MQF___P and (V)MQF___D Series are members of Mercury’s Q-Family Quick-Turn
Temperature Compensated oscillators that can be delivered within days. With low current consumption
(44 mA for LVPECL 212.500 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 for volume production ( ± 2.5 ppm over -30°C to +85°C ) .
