Single PHY Lite for Parallel Interfaces Intel® FPGA IP for Arria® 10 and Cyclone® 10 GX Devices

The following figure shows an example of the design containing a single PHY Lite for Parallel Interfaces Intel® FPGA IP for Arria® 10 and Cyclone® 10 GX devices with one bidirectional group composed of four data bits and one strobe. Refer to the Example of Identifying the Lane and Pin Addresses from Parameter Table to determine the lane and pin addresses from the parameter table.

Two PHY Lite for Parallel Interfaces Intel® FPGA IP for Arria® 10 and Cyclone® 10 GX Devices

The following figure shows an example of a design containing two PHY Lite for Parallel Interfaces Intel® FPGA IP for Arria® 10 and Cyclone® 10 GX devices, each with one bidirectional group composed of four data bits and one strobe. Both interfaces are in the same I/O column, and therefore must merge the tables.

Figure 157. Parameter Table Example for Arria® 10 and Cyclone® 10 GX Devices


Important: There is no guarantee of ordering the interface parameter tables in the merged table. You must perform a search to locate a specific interface parameter.

For more information about the contents of the parameter table, refer to the Address Lookup topic.
