First 2.5 and 5Gbit/s octal Ethernet transceiver

Marvell has announced the Alaska M 88E2180 Gigabit Ethernet transceiver, which it claims to be the first compatible with both the IEEE 802.3bz standard and the NBASE-T AllianceSM specification for 2.5 and 5Gbit/s operation over CAT5e cables.

Many enterprises have installed Ethernet CAT5e cabling typically limited to 1Gbit/s. With the Alaska M 88E2180 Gigabit Ethernet transceiver which can be deployed on existing wired infrastructure, enterprises can now benefit from the new PHY technology that the company claims can provide up to five times more data rates compared to traditional offerings.

According to the company, the Alaska M 88E2180 Gigabit Ethernet transceiver is optimised for low power consumption and design simplicity while delivering cable performance that exceeds IEEE requirements.

The company claims current solutions leverage 10Gbit/s technology for 2.5/5Gbit/s operation, resulting in an excessive power overhead, whereas the new devices are specifically targeted at 5GBASE-T/ 2.5GBASE-T / 1000BASE-T / 100BASE-TX / 10BASE-Te Ethernet designs.

The 88E21xx family also includes the Alaska M 88E2110 device, an optimised single-port five-speed multi-Gigabit PHY supplied in a 7 x 11mm FCBGA package.

The Alaska M 88E21xx family is suited for 802.11ax wireless access points, uplinks on enterprise switches and SFP+ media converters, as well as for emerging applications that can leverage Cat5e cabling such as small cell backhaul, PON residential gateways, high end personal computers and workstations.

The Alaska devices can also be coupled with the company’s Prestera switch families to provide a comprehensive solution.
