NJU6396
3rd. Over Tone Quartz Crystal Oscillator for 166MHz
sGENERAL DESCRIPTION sPACKAGE OUTLINE
The NJU6396 is a C-MOS IC for XOs, and can oscillate up to 166MHz maximum at very low operating voltage. High Fan-out is gained from low operating voltage with 3-state output buffer and the oscillation amplifier that is realized very low stand-by current using NAND circuit. Furthermore, not using PLL, the electrical character shows a very low jitter. The NJU6396 is suitable for mobile, optical communications (included WDM system) and not to mention previous applications; Computer & Peripherals, telecommunications, LAN/WAN, Wireless and so on.
