4.3.2. Model 2: Acknowledgment Model

The acknowledgment model uses an event-driven mechanism. It is used for
applications with strict timing requirements. Instead of waiting for a minimum
assertion time of 70 μs for
to receive the acknowledgment from the Transceiver Native PHY IP core to ensure
successful assertion and deassertion of the analog resets.
To enable the acknowledgment model, enable the following ports in the Transceiver
Native PHY IP core:
•
Enable the
