CF5077B1 VCXO LVPECL: 30 to 170MHz fully integrated with NPC uniquely strong vari-cap is now available. ±130ppm pullability while delivering phase noise <-125dB at 1kHz and 148dB noise floor (122.88MHz) delivers best of class performance for LTE cellular towers and wireless applications.. "The CF5077 is a proven winner offering system designers greater tolerance to system noise (PSRR) and varied capacitive loads (zero output impedance), far better than CMOS implementations." according to VC America Tom Hardy. "NPC vari-cap design lowers phase noise while delivering wide pull range needed for reliable operation. "
