1.8V Operating Voltage 3
rd
Overtone
Quartz Crystal Oscillator IC with Input Tolerant Function
■GENERAL
DESCRIPTION
The NJU6227 series is a C-MOS quartz crystal oscillator IC
rd
realized excellent frequency stability for 3 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@V
DD
±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).

■VERSION
DISCRIMINATION INTERNAL COMPONENTS
PAD layout version of the NJU6227 series is determined by the mask pattern and Notch Number. Frequency
version of the NJU6227 series is determined by the internal fuse trimming.
Type Number and PAD layout version are identified externally by the combination of the version name marking (1),
the locations of trimmed fuses (3) and The Notch number (2). (Table 1 shows the chip version identification)

●Variable
Pull-up Resistance
The CONT Terminal pull-up resistance changes in response to the input level. When CONT is tied “LOW” level, the
pull-up resistance is large, reducing the current consumed by the resistance. When CONT is left open circuit, the
pull-up resistance is small, which increases the input susceptibility to external noise. However, the pull-up
resistance ties the CONT Terminal “High” level to prevent external noise from unexpectedly stopping the output.
