VC-TXO-39SMX SERIES VC-TCXO
The VC-TXO-39SMX is a VC (Voltage Controlled) FEATURES
TCXO (Temperature Compensated Crystal
Oscillator) featuring very tight stability over
a wide temperature range. The small SMD
ceramic package measures 11.4 x 9.6 x 2.3 mm.
The voltage control has a tuning range of ± 12
• Highly stable output
• RoHS Compliant (PB Free)
• Voltage control function
• Tape and Reel (500 pcs)
ppm typical. The low profile package is ideal
for wireless communications applications.
