Transmit Data 0 through 7(GMII Mode). TXD[0:7] is presented
synchronously with the rising edge of TX_CLK1. TXD[0] is the least
significant bit of the data. When TX_EN1 is low the data on TXD should
be ignored.
MAC 1 Transmit Data 0 through 3(MII Mode – TXD1[0:3]). Four bits of
data TXD1[0:3] presented synchronously with the rising edge of
TX_CLK1.
MAC 1 Transmit Data 0 through 1(RMII Mode – TXD1[0:1]). Two bits of
data TXD1[0:1] presented synchronously with the rising edge of
TX_CLK1.
MAC 2 Transmit Data 0 through 3(MII Mode– TXD2[0:3]).Four bits of
data TXD2[0:3] presented synchronously with the rising edge of
TX_CLK2. Note that TXD2[0:3] is only available on devices with two
Ethernet ports.
MAC 2 Transmit Data 0 through 1(RMII Mode– TXD2[0:1]). Two bits of
data TXD2[0:1] presented synchronously with the rising edge of
TX_CLK2. Note that TXD2[0:1] is only available on devices with two
Ethernet ports.
MAC 1 Receive Data 0 through 7(GMII Mode). Eight bits of received
data, sampled synchronously with the rising edge of RX_CLK. For every
clock cycle, the PHY transfers 8 bits to the device. RXD[0] is the least
significant bit of the data. Data is not considered valid when RX_DV is
low.
MAC 1 Receive Data 0 through 3(MII Mode – RXD1[0:3]). Four bits of
received data, sampled synchronously with RX_CLK1. Accepted when
RX_CRS1 is asserted.
MAC 1 Receive Data 0 through 1(RMII Mode – RXD1[0:1]). Two bits of
received data, sampled synchronously with RX_CLK1. Accepted when
RX_CRS1 is asserted.
MAC 2 Receive Data 0 through 3(MII Mode – RXD2[0:3]): Four bits of
received data, sampled synchronously with RX_CLK2. Accepted when
RX_CRS2 is asserted.
MAC 2 Receive Data 0 through 1(RMII Mode – RXD2[0:1]). Two bits of
received data, sampled synchronously with RX_CLK2. Accepted when
RX_CRS2 is asserted.
Receive Clock 1 (GMII). 125MHz clock. This clock is used to sample the
RXD[7:0] data.
Receive Clock 1 (MII). Timing reference for RX_DV, RX_ERR and
RXD[3:0], which are clocked on the rising edge. RX_CLK frequency is
25MHz for 100Mbps operation and 2.5MHz for 10Mbps operation. In DTE
mode, this is a clock input provided by the PHY.
Receive Clock 2 (MII Only). Timing reference for RX_DV2, RX_ERR2 and
RXD2[3:0], which are clocked on the rising edge. RX_CLK2 frequency is
25MHz for 100Mbps operation and 2.5MHz for 10Mbps operation. In DTE
mode, this is a clock input provided by the PHY. Note that RX_CLK2 is
only available on devices with two Ethernet ports.
Transmit Clock 1 (MII). Timing reference for TX_EN1 and TXD1[3:0].
The TX_CLK1 frequency is 25MHz for 100Mbps operation and 2.5MHz
for 10Mbps operation. In DTE mode, this is a clock input provided by the
PHY. Sourced from REF_CLK Input.
Transmit Clock 2 (MII Only). Timing reference for TX_EN2 and TXD2[3:0].
The TX_CLK2 frequency is 25MHz for 100Mbps operation and 2.5MHz
for 10Mbps operation. In DTE mode, this is a clock input provided by the
PHY. Note that TX_CLK2 is only available on devices with two Ethernet
ports. Sourced from REF_CLK Input.
