OVERVIEW
The CF5034 series are differential LVPECL output oscillator ICs. They are made using a BiCMOS process which allows high-frequency oscillator circuits and differential LVPECL output circuits to be fabricated on a single chip. Two oscillator modes are supported—350MHz maximum fundamental oscillation mode, and 80MHz to 160MHz 3rd overtone oscillation mode.
The CF5034 series devices require only the connection of a crystal to realize a differential LVPECL output oscillator circuit.
