NJU6397C

NJU6397 Series 3rd. Over Tone Quartz Crystal Oscillator 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. The 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.
