VC-TX0-30SM
SERIES
TEMPERATURE COMPENSATED OSCILLATOR
The VC-TXO-30SM is a TCXO (Temperature
Compensated Crystal Oscillator) featuring very
tight stability over a wide temperature range.
The miniature SMD ceramic package measures
5 x 7 x 2.0 mm. The voltage control feature has
a frequency control range of ±5 ppm. The low
profile package is ideal for wireless communica-
tions applications.
FEATURES
• Highly stable output
• Voltage Control function
• 5 x 7 mm Footprint
•
RoHS Compliant
