NJU6369 Series
1.5V Operation Fundamental Quartz Crystal Oscillator
sGENERAL DESCRIPTION
The NJU6369 series is a C-MOS IC for fundamental quartz
crystal oscillator that consists of an oscillation amplifier,
5-stage divider and 3-state output buffer, and can oscillate at
1.5V very low voltage.
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.
The 3-state output buffer is C-MOS compatible.
