Electrical Characteristics
4.11.5.1.4
The MDC frequency is designed to be equal to or less than 2.5 MHz to be compatible with the IEEE 802.3
MII specification. However the ENET can function correctly with a maximum MDC frequency of
15 MHz.
Figure 50
shown in the figure.
4.11.5.2 RMII Mode Timing
In RMII mode, ENET_CLK is used as the REF_CLK, which is a 50 MHz ± 50 ppm continuous reference
clock. ENET_RX_EN is used as the CRS_DV in RMII. Other signals under RMII mode include
ENET_TX_EN, ENET0_TXD[1:0], ENET0_RXD[1:0] and ENET_RX_ER.
