Description
The VFTX110 is an ultra low noise high output power TCXO capable of providing an output frequency up to 1
GHz. The temperature stability is less than 1ppm over a temperature range of -40ºC to + 85ºC. The device
contains an internal voltage regulator for improved stability and noise performance. The output is configured as
a Sinewave signal which is optimal for multiplication to microwave frequencies.
