VOLTAGE CONTROLLED CRYSTAL OSCILLATOR
VCXO-B
The VCXO-B series is a tight stability, voltage controlled crystal
oscillator. The frequency can be altered pulled a minimum
±200PPM by applying a voltage between 0.5V & 4.5V to pin 1.
This oscillator is designed especially to be used in phase lock loop
applications requiring maximum frequency capture range.
For SMD package see page 66 for the F5000.
