NJU6368 Series
High Drive Fundamental Quartz Crystal Oscillator
GENERAL 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 f0,f0/2,f0/4 and f0/8 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 SOT-23-6-1.

Note2) If the supply voltage(VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V is limit specified.
Note3) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
Note4) Power Dissipation is the maximum value of a package simple substance.
