Alaska M Multi-Gigabit Ethernet PHYs


Marvell® 88E2540 Quad-Port 2.5/5GbE copper PHY 

4 ports 10/100/1000/2.5G/5GBASE-T Ethernet Transceiver with IEEE 1588v2 PTP Support

The Marvell® Alaska® 88E2540 is a fully IEEE 802.3bz/NBASE-T -compliant 4-port physical layer (PHY) device that supports IEEE 802.3az Energy Efficient Ethernet (EEE). The device supports a wide variety of host-side interfaces including MP-USXGMII (Multi-port USXGMII), USXGMII, XFI, 5GBASE-R, 2.5GBASE-X, and SGMII to support full backward compatibility with lower speed legacy Ethernet rates including 1 Gbps, 100 Mbps, and 10 Mbps. MP-USXGMII decreases the number of I/O pins on the MAC interface and lowers the overall power consumption. The 88E2540 supports one MP-USXGMII interfaces (20G-QXGMII) for four ports of 5G/2.5GBASE-T. This device family enables extremely low power across all structured wiring cable lengths, enabling dense 2.5/5G Gbps applications. The 88E2540 supports Category 5e-type cables for data rates up to 5 Gbps and distances greater than 100m

The 88E2540 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 transceiver can proactively monitor the performance of a cable and determine cable length and type. It can detect opens and shorts, then report the location of a fault. The 88E2540 has integrated 1-step/2-step PTP functionality in compliance with IEEE 1588v2 and Synchronous Ethernet (SyncE) support.
