NJU6215 Series
Low Operating Current Fundamental Quartz Crystal Oscillator IC
!GENERAL
DESCRIPTION
The NJU6215 series is a C-MOS quartz crystal oscillator IC
realized excellent frequency stability for fundamental (up to
60MHz) oscillation, and consists of an oscillation amplifier,
4-stage divider, 3-state output buffer and a built-in LDO.
The operating voltage is from 1.62V to 3.63V, and the LDO
holds down the characteristic change of the oscillation
amplifier for operating voltage variation, and has been
stabilized oscillation frequency.
The 4-stage divider generates only one frequency selected
of f

The 3-state output buffer is C-MOS compatible of high
fan-out.
The NJU6215 is suitable for the battery drive application
such as cellular phones, because it has achieved low
operating current by optimizing the tristate buffer.

) 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.
