NJU6397 Series
PRELIMINARY
3rd. Over Tone Quartz Crystal Oscillator for 135MHz
sGENERAL 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.
