GMII RX Signals
Table 5-14: GMII RX Signals
Signal Direction Width Description
gmii_rx_clk In 1 125-MHz RX clock.
gmii_rx_d[] In 8 RX data.
gmii_rx_dv In 1 When asserted, indicates the RX data is valid.
gmii_rx_err In 1 When asserted, indicates the RX data contains
error.
MII TX Signals
The signals below are present in the 10M/100B/1G/10G operating mode.
Table 5-15: MII TX Signals
Signal Direction Width Description
tx_clkena In 1 Clock enable from the PHY IP. This clock
effectively divides gmii_tx_clk to 25 MHz for 100
Mbps and 2.5 MHz for 10 Mbps.
tx_clkena_half_rate In 1 Clock enable from the PHY IP. This clock
effectively divides gmii_tx_clk to 12.5 MHz for
100 Mbps and 1.25 MHz for 10 Mbps.
mii_tx_d[] Out 4 TX data bus.
mii_tx_en Out 1 When asserted, indicates the TX data is valid.
mii_tx_err Out 1 When asserted, indicates the TX data contains
error.
MII RX Signals
The signals below are present in the 10M/100B/1G/10G operating mode.
Table 5-16: MII RX Signals
Signal Direction Width Description
rx_clkena In 1 Clock enable from the PHY IP for 100 Mbps and 10
Mbps operations. This clock effectively divides
gmii_rx_clk to 25 MHz for 100 Mbps and 2.5
MHz for 10 Mbps.
rx_clkena_half_rate In 1 Clock enable from the PHY IP for 100 Mbps and 10
Mbps operations. This clock effectively runs at half
the rate of rx_clkena and divides gmii_rx_clk to
12.5 MHz for 100 Mbps and 1.25 MHz for 10 Mbps.
The rising edges of this signal and rx_clkena must
align.
