New Japan Radio NJU6221
NJU6221 Series
1.8V Operating Voltage Fundamental
Quartz Crystal Oscillator IC with Input Tolerant Function
GENERAL DESCRIPTION
The NJU6221 series is a C-MOS quartz crystal oscillator IC
realized excellent frequency stability for fundamental (up to
60MHz) oscillation, and consists of an oscillation amplifier, a
6-stage divider, a 3-state output buffer, a built-in LDO and a
input tolerant circuit. The operating voltage is from 1.62V 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. ( ±1ppm@VDD±10%)
The 6-stage divider generates only one frequency selected
at the factory shipment of f0, f0/2, f0/4, f0/8, f0/16, f0/32 and
f0/64 internal circuits is output. The 3-state output buffer is
C-MOS compatible.
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.

Variable Pull-up Resistance
The CONT Terminal pull-up resistance changes in response to the input level. When CONT is tied LOWlevel, 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 Highlevel to prevent external noise from unexpectedly stopping the output.
