New Japan Radio NJU6394
NJU6394 Series
1.8V 125MHz 3rd Over Tone Quartz Crystal Oscillator
!GENERAL DESCRIPTION
The NJU6394 series is a C-MOS, 1.8V, 125MHz, 3rd
overtone 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 3
version, 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.

Note1) If the supply voltage(VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V is
limit specified.
Note2) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the
circuit.
