Refer to
2. Select GbE or GbE 1588 from the Transceiver configuration rules list located
under Datapath Options, depending on which protocol you are implementing.
3. Use the parameter values in the tables in
GbE and GbE with IEEE 1588v2
the protocol presets described in
GIGE-1.25 Gbps preset for GbE, and the GIGE-1.25 Gbps 1588 preset for GbE
1588. You can then modify the setting to meet your specific requirements.
4. Click Generate to generate the Native PHY IP core top-level RTL file.
Figure 52. Signals and Ports for Native PHY IP Configured for GbE or GbE with IEEE
1588v2
Generating the IP core creates signals and ports based on your parameter settings.

5. Instantiate and configure your PLL.
6. Instantiate a transceiver reset controller.
You can use your own reset controller or use the Native PHY Reset Controller IP
core.
7. Connect the Native PHY IP to the PLL IP and the reset controller. Use the
information in the figure below to connect the ports.
