6.9. Transceiver Channel Reconfiguration

You can use channel reconfiguration to dynamically reconfigure the channel in a transceiver PHY IP core. Among the settings that you can change dynamically are the data rate and interface width.

You can reconfigure the channels in the following ways:

  • Reconfigure the CDR of the receiver channel.
  • Enable and disable all static PCS sub-blocks.
  • Select an alternate PLL within the transceiver block to supply a different clock to the transceiver clock generation block.
  • Reconfigure the TX local clock divider with a 1, 2, 4, or 8 division factor.
