CF5034 series  
350MHz PECL-output Oscillator ICs  
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.

1. The recommended oscillator frequency criteria is based on the negative resistance characteristics and cutoff frequency. Note that this may change  
depending on the crystal characteristics, thus sufficient allowance should be made.
