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
