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.
