NJU6368 Series
High Drive Fundamental Quartz Crystal Oscillator
s
GENERAL DESCRIPTION
s
PACKAGE OUTLINE
The NJU6368 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
,f
0
/2,f
0
/4 and f
0
/8 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 and can
drive 50pF(@5V) C-MOS load.
Furthermore, the package is small-sized MTP-6.

Note2) If the supply voltage(V
DD
) 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.
Note4) Power Dissipation is the maximum value of a package simple substance.
