Achronix Speedster22i 10G/40G/100G Ethernet - Manual (Page 8)

8 UG029, September 6, 2013
Overview
The hardened 10/40/100 Gigabit Ethernet controller available in Achronix Speedster22i
FPGAs provides a flexible, high-performance, and power efficient networking interface.
The features include:

Fully integrated 10/40/100 Gigabit Ethernet MAC

Designed to the IEEE Std 802.3ba-2010 specification

Configurable full-duplex for 10/40/100 Gigabit Ethernet operation

5 – configurable modes of operation
o 1-12 x 10 Gigabit Ethernet Channels
o 1 x 100 Gigabit, 1-2 x 10 Gigabit Ethernet Channels
o 1-3 x 40 Gigabit Ethernet Channels
o 1-4 x 10 Gigabit, 1-2 x 40 Gigabit Ethernet Channels
o 1-8 x 10 Gigabit, 1 x 40 Gigabit Ethernet Channels

User-accessible raw statistic vector outputs (IEEE 802.3 basic, mandatory and
recommended Management Information packages (clause 30, MIB, MIB-II, IETF
RFC 2665, SNMP, RMON in accordance with IETF RFC 2819))

Provides counters to generate the applicable objects of the Management
Information Base (MIB, MIB-II) according to IETF RFC 2665 (including its update
to 10 Gbps) for SNMP (Simple Network Management Protocol) managed
environments.

Support for VLAN 802.1q VLAN Tag (VLAN Type and VLAN Info fields) frames

Configurable in-band Frame Check Sequence (FCS) field passing on both transmit
and receive paths

Auto padding on transmit and stripping on receive paths

Configured and monitored through a host interface

Each PCS Layer implements a X/XL/CGMII side loopback to the MAC, which
returns all data from the MAC transmit back to the MAC receive side without
passing through any the PCS blocks.
o 10G Base-R: The PCS transmits the constant pattern of 0x00ff
to the SerDes line interface.
o 40G/100G Base-R: The PCS transmits the MAC transmit data
unchanged to the SerDes line interface (as defined by
IEEE802.3ba).

Hardware-selectable Device Control Register (DCR) bus or generic host bus
interface

Configurable flow control through Ethernet MAC Control PAUSE frames;
symmetrically or asymmetrically enabled

Configurable support for jumbo frames of any length
