NJU6367 Series
Fundamental Quartz Crystal Oscillator
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJU6367 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 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.
NJU6367XC-D
The 3-state output buffer is C-MOS compatible.
