Integrated PoE reference design from Marvell and Microsemi

June 08, 2015 // By Graham Prophet
An integrated software, hardware and joint reference design for high-bandwidth Ethernet products, incorporating Microsemi’s Power over Ethernet (PoE) solutions, is designed to provide faster time-to-market.

Marvell is to incorporate Microsemi Corporation’s Power over Ethernet (PoE) power sourcing equipment (PSE) offering into its turnkey manufacturing-ready reference designs, bundled with software solutions. The combined technologies from Marvell and Microsemi is aimed at a range of IoT and other connected network applications including wireless access points, 4G/LTE small cells, sensors, IP cameras and lighting.

PoE, say the two companies, is one of the most widely deployed technologies to power connected devices in an enterprise and small and medium-sized enterprise (SME) environment. It is a cost-effective way to enable better communication, collaboration and ease of management without compromising ease of quick deployment.

The Marvell Prestera DX family of packet processors enables secure, high-density and intelligent 10GbE/2.5GbE/1GbE switching solutions at the access/edge and aggregation layers of campus, industrial, SME and service provider networks.

“Production-quality reference designs and tightly coupled software and hardware integration with our ecosystem partners accelerates time to market for ODMs and OEMs,” said Ron Cates, Senior Director, Product Marketing, Marvell Semiconductor, Inc. “Marvell’s Prestera DX packet processors and Alaska Ethernet PHYs in combination with Microsemi’s PoE devices are driving industry-leading solutions with PoE capabilities.”

“Microsemi is pleased to offer such a highly integrated PoE device, enabling an IEEE802.3bt ready PSE solution today,” said Iris Shuker, PoE Marketing Manager for Microsemi. “The integration between Marvell’s switches, PHYs and Microsemi’s PoE reduces overall cost, creating a best-in-class solution for enterprise and small and medium-sized enterprise markets.”

Microsemi’s sixth generation power source equipment (PSE) solution is highly integrated with only one capacitor per port. A very low port resistance (less than 350 mOhm) enables a high efficiency, low dissipation design. The architecture enables up to 95W per port. The solution is IEEE802.3 standard compliant (802.3af & 802.3at) with support for IEEE 802.3bt enabled by a software upgrade.
