在GMII接口中,TX通道参考时钟是GTX_CLK,RX通道参考时钟是RX_CLK,802.3-2005定义了它们之间的关系。 图2 GMII signal timing at receiver input 由图2可知,Spec只定义了TX通道和RX通道中接收端Setup时间和Hold时间。很明显,即该Spec只对TX通道上PHY这一侧的接收特性作了定义,而对TX通道MAC那一侧的发送特性并没...

The Cyclone V device datasheet states in Table 48 RGMII Timing Characteristics: Td (TX_CLK to TXD/TX_CTL output data delay) -0.85ns ..+0.15ns. So with the correct Clock to Data Delay it should be possible to reach the 500ps output...
图19GMIIsignaltimingatreceiverinput 由图19可知,Spec只定义了TX通道和RX通道中接收端Setup时间和Hold时间。很明显,即该Spec只对TX通道上PHY这一侧的接收特性作了定义,而对TX通道MAC那一侧的发送特性并没有定义。ICVendor可在TX通道那一侧的MAC的发送特性作适当调整,只要最终的时序满足TX通道上PHY这一侧的接收特性...
