NJU6368 Series PRELIMINARY High Drive Fundamental Quartz Crystal Oscillator GENERAL DESCRIPTION PACKAGE OUTLINE The NJU6368 series is a C-MOS fundamental quartz crystal oscillator that consists of an oscillation amplifier, 3-stage divider and 3-state output buffer. The 3-stage divider generates only one frequency selected of f ,f /2,f /4 and f /8 by internal circuits is output. 0 0 0 0 NJU6368XC-C NJU6368XF1 The oscillation amplifier is realized very low stand-by current using NAND circuit. The 3-state output buffer is C-MOS compatible and can drive 50pF( 5V) C-MOS load. Furthermore, the package is small-sized MTP-6.

Note3) Decupling capacitor should be connected between V and V due to the stabilized operation for the DD SS circuit. Note4) Power Dissipation is the maximum value of a package simple substance. 2002/12/18 ( 2 / 5 )
