Low Latency 40- and 100-Gbps Ethernet (40GbE and 100GbE) media access controller
(MAC) and PHY MegaCore
®
functions offer the lowest round-trip latency and smallest size to implement
the
IEEE 802.3ba 40G and 100G Ethernet Standard
with an option to support the
IEEE 802.3ap-2007
Backplane Ethernet Standard.
The version of this product that supports Arria
®
10 devices is included in the Altera MegaCore IP Library
and available from the Quartus
®
Prime IP Catalog.
Note:
The full product name, Low Latency 40- and 100-Gbps Ethernet MAC and PHY MegaCore
Function, is shortened to Low Latency (LL) 40-100GbE IP core in this document. In addition,
although multiple variations are available from the parameter editor, this document refers to this
product as a single IP core, because all variations are configurable from the same parameter editor.
