Drop-In PoE Connector Solution Smooths Implementation

Feb. 24, 2013
A next-generation single-port controller integrates power-device (PD) controller circuitry and Power over Ethernet (PoE) functionality that saves up to 75% of space on printed-circuit boards compared to discrete solutions, says Molex Inc.
A next-generation single-port controller integrates power-device (PD) controller circuitry and Power over Ethernet (PoE) functionality that saves up to 75% of space on printed-circuit boards compared to discrete solutions, says Molex Inc. In addition to the PoE plus power-device controller, the PDJack connector incorporates bridge rectifiers and combines them with gigabit magnetics. It supports functions of all PoE power-sourcing equipment as required for IEEE802.3at compliance, interoperability, thermal management, and EMI standards. Molex developed the connector with Microsemi, using its PD70200 PD controller, which meets all PD standards. The PDJack comes in Class 0, 1, 2, 3, and 4 and operates at 25.5 W at 37 to 57 V. Two output-power pins and standard signal pins provide Ethernet connectivity; additional pins allow power-up of an external dc-dc converter. All communications are handled with the switch/router PoE controllers to negotiate power requirements and manage safe power up and power down.MOLEX INC.
