OSCILLATORS
The F3345/F3355 are our miniature surface mount oscillators, perfect
for applications such as portable computers & peripherals,
telecommunication devices and instrumentation. These miniature
designs offer high reliability utilizing a hermetically sealed ceramic
package.

1 Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change,
aging, shock, and vibration.
3 An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
Note: A 0.01µF bypass capacitor should be placed between VDD (Pin 4) and GND (Pin 2) to
minimize power supply line noise.
See page 44 for mechanical specifications, test circuits, and output waveform.
