NJU6398

NJU6398 LVDS-output Quartz Crystal Oscillator IC !GENERAL DESCRIPTION The NJU6398 is a quartz crystal oscillator IC with LVDS output, from 110MHz to 160MHz frequency output, which consists of an oscillation amplifier, LVDS output, and 3-state output buffer for each LVDS. The oscillation amplifier realizes very low oscillation stop current with NAND circuit. The NJU6398 is suitable for mobile, optical communications (including WDM system), PC & Peripherals, telecommunications, LAN/WAN, and wireless systems !
