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 st...
