4.3.1.8. Transceiver Reconfiguration Controller

You can use the Transceiver Reconfiguration Controller IP core to change the device transceiver settings at any time.

You can selectively reconfigure any portion of the transceiver. The reconfiguration of each portion requires a read-modify-write operation (read first, then write). The read-modify-write operation modifies only the appropriate bits in a register and does not affect the other bits.

The Transceiver Reconfiguration Controller is only available and required in Arria V and Stratix V devices. Because the RX and TX transceivers share a single controller, the controller requires Platform Designer interconnects, such as Avalon-MM Master Translator and Avalon-MM Slave Translator, in the Platform Designer system.

  • The Avalon-MM Master Translator provides an interface between this controller and the RX Multirate Reconfig Controller.
  • The Avalon-MM Slave Translator arbitrates the RX and TX reconfiguration event for this controller.
