MARVELL ALASKA X 88X3240P OVERVIEW
The Marvell® Alaska® X 88X3240P is a new Ethernet transceiver that is fully IEEE 10GBASE-T
standard compliant. Manufactured with 28 nanometer (nm) lithography, the Marvell Alaska X
88X3240P enables a lower cost, low-power dissipation 10Gbps Ethernet design, eliminating the
need for exotic optical modules in mainstream applications. The IEEE 10GBASE-T standard uses
Digital Signal Processing (DSP) technology to enable the repurposing of low-cost Ethernet cables
for 10 Gigabits-per-second (Gbps) data transmission, supplanting the use of optical technology for
applications such as data center switches, storage units incorporating Fibre Channel over Ethernet
(FCoE) connectivity, servers with 4x10GE ports and enterprise switching platforms.
KEY BENEFITS
• Marvell Alaska X 88X3240P Ethernet Transceiver is a IEEE-standard compliant 10GBASE-T PHY
capable of 10Gbps data rates over Unshielded Twisted Pair (UTP) cable.
• Marvell’s first 28nm process technology Ethernet transceiver is a lower cost alternative to optical
modules and can bring 10Gbps data rates to mainstream applications.
• Enables low-power dissipation and lower cost design; backward compatible and interoperable with
legacy Ethernet standards.
PRODUCT DESCRIPTION
The Marvell Alaska X 88X3240P is a fully IEEE 802.3an 10GBASE-T-compliant 4-port physical layer
(PHY) device that supports IEEE 802.3az Energy Efficient Ethernet (EEE). The latest addition to the
Marvell portfolio of 10Gbps Marvell Alaska X transceivers, the Marvell Alaska X 88X3240P supports
the host-side XFI and RXAUI interface, with SGMII support for full backward compatibility with lower
speed legacy Ethernet rates including: 1Gbps, 100 Mbps and 10 Mbps.
The Marvell Alaska X 88X3240P is a complete single-chip solution for all Ethernet rates and achieves
industry-leading low-power consumption. The flexibility of the Marvell Alaska X 88X3240P device
enables extremely low power across all structured wiring cable lengths, enabling dense 10Gbps
applications. The Marvell Alaska X 88X3240P supports Category 6- (screened or unscreened),
Category 6a- (Augmented) and Category 7-type cables at full IEEE 802.3an range. The Marvell
Alaska X 88X3240P enables both copper and fiber applications with its unique auto-media-detect
mode. With this media plug-and-play feature the Marvell Alaska X 88X3240P can automatically
detect whether there is a SFP+ fiber link, or if there is an active copper link partner connected to the
RJ-45 (10 Gbps/1000 Mbps/100 Mbps/10 Mbps copper applications.) Depending on the preferred
media type, the Marvell Alaska X 88X3240P will automatically switch to the fiber or copper line-side
interface without any involvement from the user.
The Marvell Alaska X 88X3240P also incorporates the Marvell advanced Virtual Cable Tester (VCT)
technology for cable fault detection and proactive cable performance monitoring. With advanced
digital signal processing (DSP) the Marvell Alaska X 88X3240P can proactively monitor the
performance of a cable and determine cable length and type. It can detect opens and shorts and can
report the location of a fault.
The Marvell Alaska X 88X3240P supports the Marvell LinkCrypt® feature, which is based on the
IEEE802.1ae MACsec protocol. The Marvell Alaska X 88X3240P device also supports features
above those specified by the IEEE802.1ae MACsec protocol. These include the ability to select and
filter uncontrolled port traffic, support of packet redirection by addition of a new MAC DA, SA and
Ethertype, support of latency minimization for flow control packets and support for diagnostics,
MACsec header retention and additional statistics counters.
