NJU6315 Series
0.9V Operation Fundamental Quartz Crystal Oscillator IC
!GENERAL DESCRIPTION The NJU6315 series is C-MOS quartz crystal oscillator IC for fundamental (up to 50MHz) oscillation. The operating voltage is from 0.9V to 3.3V, and the pad layout is suitable for wire bonding mount of existing-sized ceramic package. The 5-stage divider generates only one frequency selected of f0, f0/2,f0/4 f0/8, f0/16 and f0/32 by internal circuits is output. The oscillation amplifier is realized very low stand-by current using NAND circuit. Furthermore, The 3-state output buffer is C-MOS compatible. !PACKAGE OUTLINE
