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 f

/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.

Note2) If the supply voltage(V

) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V is
limit specified.
Note3) Decupling capacitor should be connected between V
DD
and V

due to the stabilized operation for the
circuit.
