7.3. PHY Merging and Arbiter Connection

There are three aspects to this merging:
  • Location Assignments
  • XCVR_RECONFIG_GROUP Assignment
  • Common connection of the Avalon® Reconfiguration Bus – this is handled by the PHY Arbiter

The PHY Arbiter takes in the Avalon® reconfiguration bus masters from the RX and TX PHYs and arbitrates between their accesses to drive the Avalon® slave of the simplex transceiver instantiations within the RX and TX PHYs with the same signals - refer Fig 10.

There are several basic use cases of the PHYs and PHY Arbiter:

  • RX Only
  • TX Only
  • Single RX and TX simple merge
  • Complex Straddled Channels
