Use the example reset sequence shown in
dynamic reconfiguration controller to change the TX PLL settings of the transceiver
channel. In this example, the dynamic reconfiguration is used to dynamically
reconfigure the data rate of the transceiver channel configured in Basic ×1 mode with
the receiver CDR in automatic lock mode.
As shown in
dynamic reconfiguration controller to change the configuration of the transceiver
channel:
1. After power up and establishing that the transceiver is operating correctly, write
2. Assert the tx_digitalreset, rx_analogreset, and rx_digitalreset signals.
3. As soon as write_all is asserted, the dynamic reconfiguration controller starts to
