Altera Triple Speed Ethernet MegaCore Function - Manual (Page 61)

You can configure the PCS function to include an embedded physical medium attachment (PMA) with a a
serial transceiver or LVDS I/O and soft CDR. The PMA interoperates with an external physical medium
dependent (PMD) device, which drives the external copper or fiber network. The interconnect between
Altera and PMD devices can be TBI or 1.25 Gbps serial.
The PCS function supports the following external PHYs:
• 1000 BASE-X PHYs as is.
• 10BASE-T, 100BASE-T and 1000BASE-T PHYs if the PHYs support SGMII.
