Description
The VFFT100 is a Frequency Translator capable of providing an output frequency up to 1 GHz. An internal
synthesizer locks to the input reference clock and multiplies it up to the desired output frequency. An internal
voltage regulator offers improved stability and noise performance. The output configured as a differential
LVPECL signal and requires external termination resistors. The VFFT100 is available in a 25.4mm x 22 mm
surface mount package.
