1.2. About the Document

The GTS Dynamic Reconfiguration Controller IP allows you to dynamically reconfigure a subset of the transceiver channels to operate in different modes. For example, you can adjust data rates, protocols, and analog settings individually without impacting the adjacent transceiver channels.

Depending on the protocol and hardware implementation, dynamic reconfiguration (DR) may reconfigure media access control (MAC), forward error correction (FEC), and physical coding sublayer (PCS) blocks.

Additional dynamic reconfiguration features include:
  • Setting up the required reference clocks. The system clock must be constant across all profiles in a selected dynamic reconfiguration group within a quad.
  • Selecting the appropriate clocks input for each of the MAC, FEC, PCS, and transceiver blocks.
  • Setting the multiplexers to select the appropriate control and datapath for MAC/PCS/PMA/FEC-direct modes.
