ELECTRICAL SPECIFICATION OUTPUT (PIN = “R.F. OUTPUT”)
High Frequency, Very Low Noise and
Low g-Sensitivity VCXO VLEU-Type series
14 x 9mm SMD package
FEATURE
- VLEU-Type series is a high frequency high performance VCXO offering high
frequency and very low phase noise/Low g-Sensitivity. The part comes in a
small SMD package which makes it suitable for reflow soldering during pick
and place assembly.
- Low Phase Noise - Low g-Sensitivity
- Small SMD Package - Low Power Consumption
TYPICAL APPLICATION
- Instrument - Microwave Communication
- Test & Measurement - Telecom Systems
- Satellite Communication
RoHS Compliant
