Description
The VFTX215 is a low noise TCXO which provides two CMOS outputs at a frequency of 100MHz. The
temperature stability is less than 0.5ppm 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 VFTX215 is available in a
15.5 mm x 19.5 mm surface mount package.
