MAC INTERFACES | RGMII | |||
TX_CLK | 30 | O | MII TRANSMIT CLOCK: TX_CLK is a continuous clock signal driven by the PHY during 10 Mbps or 100 Mbps MII mode. TX_CLK clocks the data or error out of the MAC layer and into the PHY. | |
The TX_CLK clock frequency is 2.5 MHz in 10BASE-Te and 25 MHz in 100BASE-TX mode. | ||||
TX_D7 | 31 | I, PD | GMII TRANSMIT DATA Bit 7: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK. | |
TX_D6 | 30 | I, PD | GMII TRANSMIT DATA Bit 6: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK. | |
TX_D5 | 33 | I, PD | GMII TRANSMIT DATA Bit 5: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK. | |

In MII 4B nibble mode, assertion of Transmit Error by the controller causes the PHY to issue invalid symbols followed by Halt (H) symbols until deassertion occurs. | ||||

RX_ER / GPIO | O, PD | RECEIVE ERROR: In 10 Mbps, 100 Mbps and 1000 Mbps mode this active high output indicates that the PHY has detected a Receive Error. The RX_ER signal is synchronous with the receive clock (RX_CLK). | ||
In RGMII, the RX_ER pin is not used. | ||||
COL / GPIO | O, PD | COLLISION DETECT: Asserted high to indicate detection of a collision condition (assertion of CRS due to simultaneous transmit and receive activity) in Half-Duplex modes. This signal is not synchronous to either MII clock (GTX_CLK, TX_CLK or RX_CLK). | ||
This signal is not defined and stays low for Full-Duplex modes. | ||||
