The VFFT200 is a Frequency Translator that accepts a predetermined input frequency from 8KHz to 200MHz and provides an output frequency from 50MHz to 200MHz. In the event the input frequency is lost, the VFFT200 will automatically switch into hold-over mode and maintain the output within 10ppm of the nominal frequency. Once the input is recovered, the device automatically switches out of hold-over back to the reference input.
