SiT3808是在市场上最灵活、兼容LVCMOS/ LVTTL的压控振荡器(VCXO)。该器件支持任意组合的频率(高达80MHz),电压(1.8V,2.5V-3.3V),牵引范围(±25PPM到±1600PPM)和包装(2520、3225,5032,7050)。

它提供了低于1微微秒的抖动性能、以及在牵引范围及线性特性方面10倍优于传统石英VCXO的特性,从而简化PLL和时钟同步设计。可透过编程改变驱动能力协助工作人员降低EMI,卓越的斜率(Kv)一致性,能将导因系统PLL效能所造成的便异性达到极小化。它与传统的石英器件的足迹和控制电压是100%兼容,因此可直接取代VCXO石英振荡器,无需任何设计变更。
