25.4x22mm SMD, LVPECL
Description
The VFTX140 is a Stratum 3 TCXO capable of providing an output frequency up to 1 GHz. The temperature
stability is less than 0.28 ppm over a temperature range of 0oC to + 70oC. Operating with a +3.3 volt power
supply the device typically consumes 220 mW. The device contains an internal voltage regulator for improved
stability and noise performance. The output is configured as a differential LVPECL signal and requires external
termination resistors. The VFTX140 is available in a 25.4mm x 22mm surface mount package.
