Description
The VFJA210 is a Jitter Attenuator which provides an output frequency up to 1.3 GHz. 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 extremely low phase noise. The output signal is delivered as a sine wave
matched for a 50 Ohm load. The VFJA210 is available in a 20 mm x 20 mm surface mount package.
