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.
