TMS320C6657: TMS320C6657时钟信号不需要电平匹配吗

您好，

      可以的。TMS320C665数据手册37页有说明

      “ All differential clock inputs comply with the LVDS Electrical Specification, IEEE 1596.3-1996” 

     TMS320C6655 and TMS320C6657 Fixed and Floating-Point Digital Signal Processor datasheet (Rev. D)

    CDCE62005可以配置输出接口类型： LVPECL, LVDS, LVCMOS and Special High Swing Output Modes

    CDCE62005 3:5 Clock Generator, Jitter Cleaner with Integrated Dual VCOs datasheet (Rev. G) (ti.com.cn)
