NJU6221 Series
PRELIMINARY
1.8V Operating Voltage Fundamental
Quartz Crystal Oscillator IC with Input Tolerant Function
sGENERAL DESCRIPTION
The NJU6221 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, a
6-stage divider, a 3-state output buffer, a built-in LDO and a
input tolerant circuit.
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 6-stage divider generates only one frequency selected
of f0, f0/2, f0/4, f0/8, f0/16, f0/32 and f0/64 internal circuits is
output.
The 3-state output buffer is C-MOS compatible of high
fan-out.
The input tolerant circuit ensures that 0 to 3.63 V can be
applied to CONT terminal without regard to the supply voltage.
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.
