| 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.
