Transceiver Reconfiguration Controller Interface
50G Interlaken IP core variations that target an Arria V or a Stratix V device require an external reconfi‐
guration controller to function correctly in hardware. 50G Interlaken IP core variations that target an
Arria 10 device include a reconfiguration controller block and do not require an external reconfiguration
controller.

50G Interlaken IP core transceiver reconfiguration controller interface.
Arria 10 External PLL Interface
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.

Arria 10 Transceiver Reconfiguration Interface
The Arria 10 transceiver reconfiguration interface provides access to the registers in the embedded Arria
10 Native PHY IP core. This interface provides direct access to the hard PCS registers on the device.
This interface is available only in variations that target an Arria 10 device. In variations that target an
Arria V device or a Stratix V device, user logic reconfigures the transceivers through the transceiver
reconfiguration controller, an external block that you must instantiate in your design outside the
50G Interlaken IP core.
The Arria 10 transceiver reconfiguration interface complies with the Avalon Memory-Mapped (Avalon-
MM) specification defined in the Avalon Interface Specifications.
