Ethernet transceivers for 2.5/5 Gbps data rates over Cat5e
Providing a cost efficient, small form factor and low power dissipation, the Alaska 88E2010/40 Ethernet transceivers enable the utilization of the most common types of installed Cat5e Ethernet cabling for applications including 802.11ac Access Point uplinks, switches, servers, workstations and high-end PCs. The transceivers are designed to be compliant with the emerging IEEE 802.3bz standard and the NBASE-T Alliance specification for 2.5 Gbps and 5 Gbps data rates over Cat5e cables.
To provide a seamless system, the Alaska 88E2010/40 Ethernet transceivers can be kitted with the company’s broad range of switches, which span the range from basic Layer 2 functionality to models containing full Enterprise Class Virtualization and Layer 3+ features. These switches support anywhere from 4 to 48 NBASE-T ports, have the ability to stack with 40GbE and 100GbE uplinks and are provided with application software in turn-key packaged solutions.
“Marvell’s Alaska 88E2010/40 Ethernet transceivers are optimized to enable 2.5 Gbps and 5 Gbps uplink data rates in SMB and enterprise environments over existing Cat5e cabling, saving the cost of rewiring the installed base,” said Michael Zimmerman, Vice President and General Manager, Connectivity, Storage and Infrastructure (CSI) BU at Marvell Semiconductor, Inc. “Marvell’s Alaska 88E2010/40 technology was custom designed to provide one of the lowest power dissipation rates in one of the smallest form factors on the market to power enterprise switching and application processor solutions at a very cost effective price. They perfectly pair with Marvell’s complete family of switch silicon products, which provide comprehensive support for 4 to 48 ports of NBASE-T 2.5Gbps and 5Gbps Ethernet.”
The Alaska 88E2010/40 devices use Marvell’s advanced DSP technology to enable the repurposing of low-cost Cat5e Ethernet cables for data rates as high as 5 Gbps. The devices support Category 6 (screened or unscreened), Category 6a (augmented) and Category 7 type cables, as well as Category 5e type cables for distances up to 100m. The devices support a variety of host interfaces (2500BASE-X, 5000BASE-R, SGMII), as well as 10G host interfaces such as USXGMII interface and XFI/RXAUI with Rate-Matching. The transceiver family also features full backward compatibility with lower-speed legacy Ethernet (1000/100/10Mbps) on the line side.
The Alaska 88E2010/40 Ethernet transceivers also incorporate the Marvell advanced Virtual Cable Tester® technology for cable fault detection and proactive cable performance monitoring. With advanced DSP technology, the transceivers can proactively monitor the performance of a cable and determine cable length and type, in addition to detecting opens and shorts and reporting the location of a fault.
The transceivers offer Energy Efficient Ethernet (EEE) IEEE 802.3az for all supported data rates, a bit error rate (BER) better than 10-15, and have demonstrated reach of over 170m on Cat5e for 2.5 Gbps and over 115m for 5G mode.
