  • Description

    The NJU6227 series is a C-MOS quartz crystal oscillator IC realized excellent frequency stability for 3rd Overtone (up to 160MHz) oscillation, and consists of an oscillation amplifier, a 3-state output buffer, a built-in LDO and a input tolerant circuit. The operating voltage is from 1.62V to 3.63V (x3, x4, x5, x6: from 2.25V 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 (Frequency stability ±1ppm@VDD±10%). 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, therefore, it is suitable for the portable items of the communication equipment and the like. The 3-state output buffer is C-MOS compatible. The NJU6227A/D version are available for driving light loads (15pF load) and NJU6227C version are available for driving heavy loads (30pF load).
