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
www.DataSheet4U.csoimngle 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.
