VVOCLTAXGEOCO-NCTROLLED CRYSTAL OSCILLATOR
The VCXO-C series is a tight stability, voltage controlled crystal
oscillator. The frequency can be pulled a minimum ±100PPM by
applying a voltage between 0.5V & 4.5V to pin 1. This oscillator is
designed to be used in applications requiring a general purpose
VCXO with excellent cost vs performance characteristics.
