VC-TXO-35SM
SERIES
VC-TCXO
The VC-TXO-35SM is a VC (Voltage
Controlled) TCXO (Temperature
Compensated Crystal Oscillator) featuring
very tight stability over a wide temperature
range. The small subminiature SMD ceramic
package measures 3.2 x 5.0 x 1.5 mm. The
voltage control has a tuning range of ± 5 ppm
minimum. The low profile package is ideal for
wireless communications applications.
FEATURES
• Highly stable output
• Wide temperature
• Voltage control function
• Small footprint
• Tape and Reel (1,000 pcs.)
• PbFree/RoHS Compliant
