1.0 pS Phase Jitter ( typical )

The (V)MQF326T , (V)MQF326P and (V)MQF326D 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 PECL 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 ) .
