AI服务器光模块对于晶振的需求

2025-11-07 11:49:05

光模块晶振作用；光模块内部晶振主要是给DSP提供高精度、高稳定性的参考时钟频率，常用频率为20、40、50、156.25MHz。光模块晶振趋势：随着光模块传输速率越高，对于晶振的稳定性、频率要求也越高。差分晶振相比单端晶振，输出信号一般为LVDS、LVPEC等信号，抗干扰能力强，可以消除共模噪声。通常400/800G光模块使用100-200MHz有源差分振荡器。光模块晶振规模：一般单个400/800G光模块至少配置1个有源差分晶振。若光模块需进行更复杂的功能和处理，可能会使用多个晶振来支持不同的时钟需求和数据处理。由于有源差分晶振需要使用超高频晶片（50MHz以上），超高频晶片核心在于MEMS工艺。目前全球具备MEMS工艺能力厂商包括日系的爱普生、NDK、KDS以及国内的泰晶科技，台系厂商晶技主要用传统工艺实现超高频晶片量产。
