Table 91.  1.25 Gbps MDI Interface Signals
Name I/O Description
ref_clk I 125 MHz local reference clock oscillator.
rx_p I Serial Differential Receive Interface.
tx_p O Serial Differential Transmit Interface.
Note: The Triple-Speed Ethernet IP with LVDS I/O must be instantiated once per bank of the LVDS I/O ports. For example, if the design uses two banks of LVDS I/Os, you must instantiate two separate Triple-Speed Ethernet IPs, one for each bank.
