Hello,
In 10G E MAC example design which is available in Altera/IP/Ethernet/altera_eth_10g_design_example/altera_eth_10g_mac_base_r. In this example design 10G E MAC and 10G BASE-R Phy are used and if you observe in this document "https://www.altera.com/content/dam/altera-www/global/en_US/pdfs/literature/ug/10gbps_mac.pdf" page number 24, there are two PHY's. 1. 10G BASE-R PHY/ XAUI PHY 2.External PHY I'M confused with this External PHY. In the design example already there is 10GBASE -R PHY with 10G-EMAC, but why this External PHY is used. Please let me know the application of this external PHY. regards VinodLink Copied
If not mistaken the IP allow use to instantiate only the MAC portion, then you will need to hook it up with external PHY chip.
