NJU6314 Datasheet, PDF (1/6 Pages) New Japan Radio – High Frequency-Stability Fundamental Quartz Crystal Oscillator IC

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.
