Description
The VFJA130 is a Jitter Attenuator capable of prov iding an output frequency up to 180MHz. An internal
synthesizer locks to the input reference clock and mult iplies it up to the desired output frequency. The output
frequency is determined by a VCXO designed for a wide pull range. An internal voltage regulator offers
improved stability and noise performance. The output is configured as a CMOS. The VFJA130 is available in a
25.4mm x 22 mm surface mount package.
