RMII does not use external signal RX_CLK as can be seen on lwip examples. The trick is that the EMAC processing data on CORE_CLK or AIPS_PLAT_CLK (depends on part number), which has higher frequency. EMAC is Synopsis IP and there are no more other information than in ...
that's the condition defined by the IP provider. Notes in Table 550 can be reformulated this way: both EMAC_TX_CLK and EMAC_RX_CLK should have 25 MHz independently of MII/RMII setup (for 100 Mbps), or 2.5 MHz (for 10 Mbps). Best regards, Pavel 1 Kudo Reply Post...

解決済み: Hi, NXP When using the RMII mode of the EMAC module in S32K3x4, why is it necessary to configure MII_RX_CLK to 25MHz? If configured to 50MHz,
