2.6.2.2. How to Implement 10GBASE-R and 10GBASE-R with IEEE 1588v2 in
Intel Cyclone 10 GX Transceivers
You should be familiar with the 10GBASE-R and PMA architecture, PLL architecture,
and the reset controller before implementing the 10GBASE-R or 10GBASE-R with IEEE
1588v2 Transceiver Configuration Rules.
You must design your own MAC and other layers in the FPGA to implement the
10GBASE-R or 10GBASE-R with 1588 Transceiver Configuration Rule using the Native
PHY IP.
1. Instantiate the Intel Cyclone 10 GX Transceiver Native PHY IP from the IP
Catalog.
Refer to
2. Select 10GBASE-R or 10GBASE-R 1588 from the Transceiver configuration
rule list located under Datapath Options, depending on which protocol you are
implementing.
3. Use the parameter values in the tables in
the 10GBASE-R Protocol
described in
for 10GBASE-R with IEEE 1588v2. You can then modify the settings to meet
your specific requirements.
4. Click Generate to generate the Native PHY IP core RTL file.

Notes:
1. For 10GBASE-R with 1588 configurations, this signal is user-controlled.
2. For 10GBASE-R with 1588 configurations, this signal is connected from the output of TX FIFO in the FPGA fabric.
