TX-280
Temperature Compensated Crystal Oscillator
TX-280
Description
Vectron International has introduced a series of surface mount, Temperature Compensated Crystal Oscillators (TCXO) available in
The TX-280 surface mount TCXO’s can be mounted using the standard convection re!ow process. The units can meet the 0.ꢀ3
holdover requirement of GR-1244-CORE table ꢀ-1 from 0 °C to +30 °C temperature range and operate from ꢀ.ꢀV or 5.0V supply.

Notes:
1. Contact factory for improved stabilities or additional product options. Not all options and codes are available at all
frequencies.
2. Unless other stated all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency
control voltage, load, temperature (25°C).
ꢀ. Phase noise degrades with increasing output frequency.
4. Subject to technical modi$cation.
5. Contact factory for availability.
