5.8.5. Transceiver Reconfiguration Interface
You can reconfigure the transceiver to accept single reference clock. The single reference clock is a 135 MHz clock for all DP1.4 bit rates: RBR, HBR, HBR2, and HBR3. DP2.0 uses the reference clock at 100 MHz for all UHBR link rates.
During run-time, you can reconfigure the transceiver to operate in either one of the bit rates by changing TX PLL divide ratio.
When the IP makes a request, the tx_reconfig_req port goes high. The user logic asserts tx_reconfig_ack and then reconfigures the transceiver. During reconfiguration, the user logic holds tx_reconfig_busy high. The user logic drives it low when reconfiguration completes.
