The following table shows the transceiver I/O ports.
| Name | I/O | Clock Domain | Description |
|---|---|---|---|
| GT_reset | I | Async | Active-High reset for the transceiver startup FSM. Note that this signal also initiates the reset sequence for the entire 10G/25G Ethernet IP core. |
| refclk_n0 | I | Refer to Clocking. | Differential reference clock input for the SerDes, negative phase. |
| refclk_p0 | I | Refer to Clocking. | Differential reference clock input for the SerDes, negative phase. |
| rx_serdes_data_n0 | I | Refer to Clocking. | Serial data from the line; negative phase of the differential signal. |
| rx_serdes_data_p0 | I | Refer to Clocking. | Serial data from the line; positive phase of the differential signal. |
| tx_serdes_data_n0 | O | Refer to Clocking. | Serial data to the line; negative phase of the differential signal. |
| tx_serdes_data_p0 | O | Refer to Clocking. | Serial data to the line; positive phase of the differential signal. |
| tx_serdes_clkout | O | Refer to Clocking. | When present, same as tx_clk_out. |
