NJU6368 Series
PRELIMINARY
High Drive Fundamental Quartz Crystal Oscillator
sGENERAL DESCRIPTION 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 0,f0/2,f 0/4 and f 0/8 by internal circuits is output. 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. sFEATURES qOperating Voltage 2.7 to 5.5V qMaximum Oscillation Frequency 50MHz qLow Operating Current qHigh Fan-out IOH/IOL=8mA@3.3V IOH/IOL=16mA@5.0V q3-Stage Divider Maximum Divider f 0/8 qOscillation Stop and Output Stand-by Function q3-State Output Buffer qOscillation Capacitors Cg and Cg on-chip qPackage Outline Thin-Chip/MTP-6 qC-MOS Technology sPACKAGE OUTLINE
