【经验】浅析国产IIC可编程硅振AS5003频率、输出格式的配置方式
南京益昂AS5003系列是IIC可编程硅振,支持用户各种规格,包括频率、输出格式和DCO模式。南京益昂硅振不同于石英、MEMS传统的晶振需要晶体、陶瓷底座、振荡IC组成,其内部仅有一个 CMOS IC组成,单硅片结构,交期迅速,采用LC谐振电路作为本振,抗震,无停振风险。广泛应用于光模块、FPGA时钟上。
益昂AS5003可支持输出单端频点10 kHz to 212.5 MHz,差分频点10 kHz to 350 MHz,可选择的LVPECL, LVDS, CML, HCSL, CMOS, or Dual CMOS 输出,下面将介绍频率、输出格式的配置方式。
AS5003软件驱动程序,修改频率或输出格式配置规格书Section 5.4,通过修改对应寄存器,即可灵活配置频率计划。

光模块PCB和光器件仿真概述
光模块PCB和光器件的仿真属于高速串行数据链路(high speed serial data link)仿真的一个小分支,涉及的东西相对比较少,一般只要能扎实的练习一个光模块仿真例子,不管是QSFP28还是CFP2的,其他类型模块的仿真都能应付,毕竟模块里面的东西都是大同小异。稍微要注意的是,光器件的仿真设计到光电转换(EO\OE),如何在仿真上准确的复现这种转换过程,就需要一些经验的积累。
