Product Brief

Marvell 88E2580 Octal-Port 2.5/5GbE copper PHY

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

Overview

The Marvell® Alaska® 88E2580 is a fully IEEE 802.3bz/NBASE-T

-compliant 8-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 88X3580 supports two MP-USXGMII

interfaces (20G-QXGMII) for eight ports of 5G/2.5GBASE-T.

applications. The 88E2580 supports Category 5e-type cables

for data rates up to 5 Gbps and distances greater than 100m.

The 88E2580 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 88X3580 has integrated 2-step PTP functionality in

compliance with IEEE 1588v2 and Synchronous Ethernet

(SyncE) support.

This device family enables extremely low power across all

structured wiring cable lengths, enabling dense 2.5/5G Gbps
