NJU6227 Series
1.8V Operating Voltage 3rd Overtone
Quartz Crystal Oscillator IC with Input Tolerant Function
GENERAL DESCRIPTION
The NJU6227 series is a C-MOS quartz crystal oscillator IC
realized excellent frequency stability for 3rd Overtone (up to
160MHz) oscillation, and consists of an oscillation amplifier,
a 3-state output buffer, a built-in LDO and a input tolerant
circuit.
The operating voltage is from 1.62V to 3.63V (x3, x4, x5, x6:
from 2.25V to 3.63V), and the LDO holds down the
characteristic change of the oscillation amplifier for operating
voltage variation, and has been stabilized oscillation
frequency (Frequency stability ±1ppm@VDD±10%).
The input tolerant circuit ensures that 0 to 3.63 V can be
applied to CONT terminal without regard to the supply voltage.
The oscillation stopping current is very low stand-by mode,
therefore, it is suitable for the portable items of the
communication equipment and the like. The 3-state output
buffer is C-MOS compatible. The NJU6227A/D version are
available for driving light loads (15pF load) and NJU6227C
version are available for driving heavy loads (30pF load).
