NJRC NJU6397A

NJU6397 Series
PRELIMINARY
3rd. Over Tone Quartz Crystal Oscillator for 135MHz
■GENERAL DESCRIPTION
The NJU6397 series that is a C-MOS IC for quartz
crystal oscillator consists of an oscillation amplifier and
3-state output buffer.
This series has three types of A, B and C. The
frequency range of the A type is from 75 to 90MHz, and
the B type is from 90 to 110MHz, and the C type is from
110 to 135MHz.
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 do not over the VDD level.
Note2) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the
circuit.
