6.3.8 RGMII Interface

DP83TD510E offers RGMII MAC interface as defined by Reduced Gigabit Media Independent Interface (RGMII) as specified by RGMII version 2.0. RGMII is designed to reduce the number of pins required to connect the MAC and PHY. To accomplish this goal, the control signals are multiplexed. Both rising and falling edges of the clock are used to sample the control signal pin on the transmit and receive paths. For 10-Mbps operation, RX_CLK and TX_CLK operate at 2.5 MHz. The timing specifications are relaxed compared to RGMII 1000M interface specifations. Refer to timing sections on timing specifications for this mode.
