GENERAL DESCRIPTION
s
PACKAGE OUTLINE
The NJU6363 series is a C-MOS fundamental quartz crystal
oscillator that consists of an oscillation amplifier, 3-stage
divider and 3-state output buffer.
The 3-stage divider generates only one frequency selected
of f
0

/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.

) 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
SS
due to the stabilized operation for the
circuit.
