General Description

The NJU6394 series is a C-MOS, 1.8V, 125MHz, 3rdovertone quartz crystal oscillator that consists of an oscillation amplifier (low oscillation-stop current based on NAND circuit) and 3-state output buffer (C-MOS compatible, 15pF load).The operating voltage is from 1.6V to 3.0V, and frequency range is from 75MHz to 125MHz divided by 3version, A-type: 75MHz to 90MHz, B-type: 90MHz to 105MHz, C-type: 105MHz to 125MHz.The oscillation amplifier realizes very low oscillation stop current with NAND circuit.The 3-state output buffer is C-MOS compatible.
