NJU62221
NJU62221 is Quartz Crystal Oscillator IC manufactured by New Japan Radio.
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,...
