[原创] IDT 8V49NS0312 12路2.5 GHz时钟发生器解决方案

IDT公司的8V49NS0312是FemtoClock® NG 12路时钟发生器:11个差分(LVPECL或LVDS)和1个LVCMOS,提供各种频率配置和输出格式,以优化相位噪音性能.差分输出频率从10.91 MHz到2.5 GHz,LVCMOS频率250MHz,相位抖动小于100fs,集成了OTP非易失性存储器,主要用在如10Gb,40Gb和100Gb以太网系统等通信和数据通信市场.本文介绍了8V49NS0312主要特性,功能框图,应用电路图以及评估板EVK-8V49NS0312主要特性和电路图.

The IDT® 8V49NS0312 enables the high-performance timing needed for complex system environments such as those seen in 10, 40 and100 Gigabit Ethernetsystems.

The 8V49NS0312 is a flexible Clock Generator with a total of four output dividers: three integer and one that is either integer or fractional. When used with an external crystal, the 8V49NS0312 generates high-performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise, such as 10, 40 and 100GE. The device is offered in a lead-free 64-VFQFN package and is designed to operate across full industrial temperature range.
