Description
The VFFT120 is a Jitter Attenuator capable of providing an output frequency up to 200 MHz. An internal
synthesizer locks to the input reference clock and multiplies it up to the desired output frequency. The output
frequency is determined by a VCXO designed for low phase noise.The +5 Volt option has an internal voltage
regulator for improved stability and noise performance. The output is configured to provide an AC coupled sine
wave into a 50 Ω load. The VFFT120 is available in a 25.4mm x 22 mm surface mount package.
