This section describes the performance of the GMII to RGMII core.

Maximum Frequencies

The GMII to RGMII core operates at 125 MHz. The Management module operates at 200/300/375 MHz.

Latency

The following measurements are for the core only and do not include any IOB registers.

Transmit Path

As measured from a data octet input into gmii_txd[7:0] of the transmitter side of the GMII interface until that data appears on the rgmii_txd[3:0] on the RGMII interface, the latency through the core through the transmit direction is one clock period of gmii_tx_clk_int.

Receive Path

Measured from a data octet input into rgmii_rxd[3:0] of the receiver side of the RGMII interface until that data appears on the gmii_rxd[7:0] on the GMII interface, the latency through the core through the receive direction is one clock period of rgmii_rx_clk, plus the additional delay equal to the fixed delay specified on the IDELAY component.

Throughput

The GMII to RGMII core operates at full line rates of 10/100/1000 Mb/s.
