1.8V Operating Voltage Fundamental Quartz Crystal Oscillator IC
!GENERAL DESCRIPTION
The NJU6212 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 f0,f0/2,f0/4 and f0/8 internal circuits is output.
The 3-state output buffer is C-MOS compatible of high
fan-out.
The oscillation stopping current is very low stand-by mode
below 10uA, therefore, it is suitable for the portable items of
the communication equipment and the like.
