NJU6315 Datasheet, PDF (1/4 Pages) New Japan Radio – 0.9V Operation Fundamental Quartz Crystal Oscillator IC

NJU6315 Series
0.9V Operation Fundamental Quartz Crystal Oscillator IC
!GENERAL DESCRIPTION
The NJU6315 series is C-MOS quartz crystal oscillator IC
for fundamental (up to 50MHz) oscillation.
The operating voltage is from 0.9V to 3.3V, and the pad
layout is suitable for wire bonding mount of existing-sized
ceramic package.
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.
Furthermore, The 3-state output buffer is C-MOS
compatible.
