1 Low Operating Fundamental Quartz Crystal Oscillator IC GENERAL DESCRIPTION The NJU66 series is a C-MOS IC for fundamental quartz crystal oscillator that consists of an oscillation amplifier, -stage divider and -state output buffer. The operating voltage is from.8 to.6 and high frequency-stability based on most suitable oscillation circuit including Cg, Cd and Rf. The -stage divider generates only one frequency selected of f,f /,f / f /8, f /6 and f / by internal circuits is output. The oscillation amplifier is realized very low stand-by current using NAND circuit, and the operating current is lower than.ma at. and 6MHz. The -state output buffer is C-MOS compatible.
