Description
The VFTX160 is a Stratum 3 TCXO capable of providing a CMOS output frequency up to 200MHz. The
temperature stability is less than 0.280 ppm over a temperature range of 0 ºC to + 70 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 VFTX160 is available in a 25.4mm x 22 mm surface mount
package.
