GENERAL DESCRIPTION

s

PACKAGE OUTLINE

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.

The 6-stage divider generates only one frequency selected

output.

The 3-state output buffer is C-MOS compatible of high

fan-out.

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

below 10uA, therefore, it is suitable for the portable items of

the communication equipment and the like.
