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.
Note:
This user guide documents the 16.0 version of the Altera Low Latency 40- and 100-Gbps Ethernet
MAC and PHY IP core that targets a Stratix
®
V device or an Arria
®
10 device. For the 16.1 release
and beyond, two IP core user guides are available to document the Low Latency 40-Gbps Ethernet
IP core and the Low Latency 100-Gbps Ethernet IP core separately. These two user guides
document the variations that target an Arria 10 device. As of 2017.12.28, the 16.0 version of the
Stratix V Low Latency 40-100GbE IP core is the most recent Stratix V Low Latency 40-100GbE IP
core available in the Self-Service Licensing Center and this user guide provides its most current
documentation.
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.
