VFFT100 Frequency Translator to 1GHz 25.4x22mm SMD, PECL/LVPECL Features ¾ ¾ ¾ ¾ RoHS Status 1.0 GHz Output Frequency Range Ultra Low Jitter and Phase Noise: -118 dBc/Hz @ 1KHz Low Power: <220mW typical Low Profile SMD package Applications ¾ ¾ ¾ Sonet / SDH / ATM 10 Gigabit Ethernet Forward Error Correction (FEC) 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.
