Product Brief
Marvell® 88X3540 Quad-Port 10GbE copper PHY
4 ports 10/100/1000/2.5G/5G/10GBASE-T Ethernet Transceiver with IEEE 1588v2 PTP
Support
Overview
The Marvell® Alaska® 88X3540 is a fully IEEE 802.3an
10GBASE-T or 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
88X3540 supports two MP-USXGMII interfaces (20G-DXGMII)
for four ports of 10GBASE-T or one MP-USXGMII interfaces
(20G-QXGMII) for four ports of 5G/2.5GBASE-T.
applications. The 88X3540 supports Category 6- (shielded or
unshielded), Category 6A- (Augmented) and Category 7-type
cables at full IEEE 802.3an range as well as Category 5e-type
cables for data rates up to 5 Gbps and distances greater than
100m.
The 88X3540 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 88X3540 has integrated 1-step/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 10 Gbps
