Description
The VFTX130 is a low noise TCXO capable of providing a CMOS output frequency up to 180MHz. The
temperature stability is less than 1ppm over a temperature range of -40 ºC to + 85 ºC. Operating with a +3.3 volt
power supply the device typically consumes 135 mW. The device contains an internal voltage regulator for
improved stability and noise performance. The VFTX130 is available in a 25.4mm x 22 mm surface mount
package.
