1G Ethernet Whitebox PHY IP

Description and Features

1G Ethernet PHY IP Core is available for licensing as a Whitebox IP, with unlimited usage and full modification rights granted to the customer, ensuring a high level of flexibility with the deliverables.

The GbE PHY IP for Giga 10/100/1000 Ethernet applications is a highly integrated solution including the Twisted Pair Physical Medium Dependent Sub-layer (TP-PMD, 100BASE-TX only), Physical Coding Sub-layer (PCS), and Physical Medium Attachment Layer (PMA). It supports 10BASE-T, 100BASE-TX, and 1000BASE-T protocols with a very low power consumption and area. The Media Access Control Layer (MAC) is connected to this GPHY via GMII (Giga Media Independent Interface) or via RGMII. It supports Unshielded Twisted Pair Category 5 Cable (UTP5), or UTP5/UTP3 cable. The Gigabit physical layer function is defined by IEEE 802.3ab and IEEE 802.3u.
