  • 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 f0/8 and f0/16 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.
