V2.0相对于V1.3引入了CLK Delay,具体的调测减文档: TI RGMII Interface Timing Budgets 原理图设计 RGMII信号连接如下图(图中PHY的TX和RX按按照MAC侧定义的,即MAC的TX应连接PHY的RX,MAC的RX连接PHY的TX): RGMII各信号的定义见下表: 电平转换:RGMII电平一般有1.8V、2.5V和3.3V三种,MAC和PHY尽量配置成同样的...
Texas Instruments Incorporated RGMII Interface Timing Budgets 1 Introduction www.ti.com 1 Introduction The reduced gigabit media independent interface (RGMII) has become a widely used alternative to the gigabit media independent interface (GMII) by offering lower pin count which enables board space, and...
如果enable自动协商模式,要确认下link partner是否也是支持千兆速率。 寄存器0x0086 配置的TX和RX的delay是多少?参考这篇RGMII Interface Timing Budgets应用手册: https://www.ti.com/lit/an/snla243/snla243.pdf

It is particularly important in the RGMII interface where the high speed clock needs to synchronize the data on RX and TX lines with maximum allowed skew of 500 ps. See the RGMII Interface Timing Budgets application report. The output channel-to-channel skew for A-to-B direction rising-edge...
