NJRC NJU6314

NJU6314 Series
High Frequency-Stability Fundamental Quartz Crystal Oscillator IC
!GENERAL DESCRIPTION
The NJU6314 series is a C-MOS IC for fundamental quartz
crystal oscillator that consists of an oscillation amplifier,
6-stage divider and 3-state output buffer.
The operating voltage is from 2.0V to 3.6V and high
frequency-stability based on most suitable oscillation circuit
including Cg, Cd and Rf.
The 6-stage divider generates only one frequency selected
of f0,f0/2,f0/4 f0/8, f0/16 f0/32 and f0/64 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.

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.
