[原创] Silabs Si5332低功耗6－8－12路输出可编时钟发生方案

Silabs公司的Si5332是低功耗6/8/12路输出可编时钟发生器,采用灵活的频率合成技术,可产生具有极好抖动性能(230 fs rms)的任何组合的输出频率,差分输出频率5-312.5MHz, LVCMOS输出频率5-170MHz,每个输出格式为LVDS, LVPECL, HCSL,LVCMOS,工作温度–40 到 +85℃,主要用在服务器,存储器和搜索加速器,以太网交换和路由器,打印图像,通信,广播视频,测试测量以及小型蜂窝,移动网络.本文介绍了Si5332主要特性,6/8/12路输出功能框图,以及评估板Si5332-12EX-EVB框图和电路图,材料清单和PCB设计图.

Highly Integrated, Low-Power Clock ICs from Silicon Labs Simplify Timing for Demanding 10/25/100G DesignsBased on Silicon Labs proprietary MultiSynth™ flexible frequency synthesis technology,the Si5332 generates any combination of output frequencies with excellent jitter performance(230 fs rms). The device ’s highly flexible architecture enables a single device togenerate a wide range of integer and non-integer related frequencies on up to 12 differentialclock outputs with 0 ppm frequency synthesis error. The device offers multiplebanks of outputs that can each be tied to independent voltages, enabling usage in mixed-supply applications. Further, the signal format of each clock output is user-configurable.
