4.2.3. Supported Ethernet Variants
The eCPRI Intel FPGA IP pairs together with the 25G/10G Ethernet. The eCPRI IP is validated together with the 25G Ethernet for Intel® Stratix® 10 designs.
- Select Ethernet Rate if you use E-tile Hard IP for Ethernet Intel FPGA IP.
Note: This option is not available with 25G Ethernet Intel FPGA IP. Use Enable 10G/25G dynamic rate switching for 10G data rate.
- Enable Enable IEEE 1588 parameter to support client PTP message and eCPRI one-way delay measurement. The 25G Ethernet MAC only supports 96-bit (V2) timestamp format.
- Disable Enable preamble pass-through and Enable TX CRC pass-through parameters.
- Turn on Enable 10G/25G dynamic rate switching option to switch between 10G and 25G data rates.
For your Intel® Arria® 10 designs, you can use Low Latency Ethernet 10G MAC Intel FPGA IP and 1G/10GbE and 10GBASE-KR PHY Intel FPGA IP to implement MAC and PHY respectively for your Ethernet.
