Description
The VFTX210 is a low noise TCXO capable of providing a sine wave output frequency up to 1 GHz. The
temperature stability is less than 1ppm over a temperature range of -40ºC to + 85ºC. Operating with a +3.3 volt
power supply the device typically consumes 240mW. The device contains an internal voltage regulator for
improved stability and noise performance. The VFTX210 is available in a 20.0 mm x 20.0 mm surface mount
package.
