Transceiver Reconfiguration Controller Interface Signals

100G 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. 100G Interlaken IP core variations that target an

Arria 10 device include a reconfiguration controller block and do not require an external reconfiguration

controller.

interface.

Bus from the external transceiver reconfiguration

controller to the 100G Interlaken IP core. The bus

includes signals fro multiple transceiver reconfigura‐

tion interfaces. The reconfiguration controller has one

interface to control each transceiver channel (one per

Interlaken lane) plus one interface to control each TX

PLL configured in the IP core. The width of each

reconfiguration controller output reconfiguration

interface is 70 bits.

reconfig_from_xcvr

Output

46 bits

per

reconfi‐

guration

interface

Bus to the external transceiver reconfiguration

controller from the 100G Interlaken IP core. The bus

includes signals for multiple reconfiguration

interfaces of the transceiver reconfiguration

controller. The reconfiguration controller has one

interface for each transceiver channel (one per

Interlaken lane) plus one interface for each TX PLL

configured in the IP core. The width of each reconfi‐

guration controller input reconfiguration interface is

46 bits.

Arria 10 External PLL Interface Signals

100G Interlaken IP core variations that target an Arria 10 device require an external transceiver PLL to

function correctly in hardware. 100G 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.
