NJU6364 Series
High Frequency-Stability Fundamental Quartz Crystal Oscillator IC
sGENERAL DESCRIPTION
The NJU6364 series is a C-MOS IC for fundamental quartz
crystal oscillator that consists of an oscillation amplifier,
5-stage divider and 3-state output buffer.
The operating voltage is from 2.0V to 3.6V and high
frequency-stability based on most suitable oscillation circuit
including Cg, Cd and Rf.
The 5-stage divider generates only one frequency selected
of f0,f0/2,f0/4 f0/8, f0/16 and f0/32 by internal circuits is output.
The oscillation amplifier is realized very low stand-by
current using NAND circuit.
The 3-state output buffer is C-MOS compatible.
