* Inclusive of 25˚C tolerance, operating temperature range, input voltage change, load change, aging shock and vibration.
Note: A 0.01~0.1 µF bypass capacitor should be placed between Vcc (Pad 6) and GND (Pad 3) for stable oscillation and to minimize power line noise.

The ECS-VXO-73 (3.3V) and ECS-VXO-75
(5.0V) are miniature VCXO'S voltage
controlled crystal oscillators with tri-state in
a ceramic SMD package. The low profile
package is ideal for todays advanced portable
PC and instrumentation applications.
