TX-191
Temperature Compensated Crystal Oscillator
TX-191
Description
Vectron International has introduced a series of surface mount, Temperature Compensated Crystal Oscillators (TCXO) available in
The TX-191 surface mount TCXO’s can be mounted using the standard convection re ow process. The units can meet the
±0.37
holdover requirement of GR-1244-CORE table 3-1 from 0 °C to +70 °C temperature range and operate from 3.3V or 5.0V supply.
