5.6.2. Intel® Arria® 10 External PLL Interface Signals
50G Interlaken IP core variations that target an Arria 10 device require an external transceiver PLL to function correctly in hardware. 50G Interlaken IP core variations that target an Arria V or Stratix V device include the transceiver PLLs and do not require that you configure any additional PLLs.
