3.3. Transceiver Reference Clock Frequency

The Transceiver reference clock frequency parameter specifies the expected frequency of the pll_ref_clk input clock.

If the actual frequency of the pll_ref_clk input clock does not match the value you specify for this parameter, the design fails in both simulation and hardware.

The 50G Interlaken IP core supports the following pll_ref_clk frequencies: 156.25 MHz, 195.3125 MHz, 250 MHz, 312.5 MHz, 390.625 MHz, 500 MHz, and 625 MHz.

The default value of the Transceiver reference clock frequency parameter is 312.5 MHz.
