然而,DFI可以在PHY相对于MC以频率倍数运行的系统中使用。 此外,DFI规范还包括一个可选的协议,用于处理系统频率变化。符合DFI要求并不要求支持此协议。 来看一下这个简图: 关于这部分协议,详细你需要使用的话请参考: DDR-PHY-Interface-Specification-v3-0.pdf[1] DDRPHY-Interface-Specification

The DDR PHY Interface specification does not specify timing values for signaling between the MC and the PHY. The only requirement is that the DFI clock must exist, and all signals defined by the DFI are required to be driven by registers referenced to a rising edge of the DFI clock. ...
