For recommended operating conditions, see
RX_CLK clock period
RX_CLK duty cycle
RXD[7:0], RX_DV, RX_ER setup time to RX_CLK
RXD[7:0], RX_DV, RX_ER hold time to RX_CLK
RX_CLK clock rise time (20%–80%)
RX_CLK clock fall time (80%–20%)
Note:
1. The frequency of RX_CLK should not exceed frequency of gigabit Ethernet reference clock by more than 300 ppm
2. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing
