4.3.2.5. Dynamic Reconfiguration of Receiver Channel Using the Acknowledgment Model

The numbers in this list correspond to the numbers in the following figure.

  1. Assert rx_analogreset and rx_digitalreset while rx_cal_busy is low.
    1. Wait for rx_analogreset_ack to go high, to ensure successful assertion of rx_analogreset. rx_analogreset_ack goes high when TRS has successfully completed the reset request for assertion.
    2. Deassert rx_analogreset.
  2. Wait for rx_analogreset_ack to go low, to ensure successful deassertion of rx_analogreset. rx_analogreset_ack goes low when TRS has successfully completed the reset request for deassertion.
  3. Ensure rx_is_lockedtodata signal goes high after the CDR is locked to data. Wait for rx_analogreset_ack to go low before monitoring rx_is_lockedtodata signal.
  4. Deassert rx_digitalreset after a minimum of tLTD (minimum of 4 μs) after rx_is_lockedtodata goes high.
