+12V Power-Over-Ethernet Application Kit - Hardware Reference
2 Detailed description
2.1 POE_12V_JS_0
2.1.1 Mechanical
The POE_12V_JS application kit is designed to provide an IEEE802.3af compliant, Power over
Ethernet (PoE) 12V power supply. This application kit is based on the National Semiconductor
LM5070 device.
The LM5070 is a power interface port and pulse width modulation(PWM) controller used in
Powered Devices (PD) that connect into Power over Ethernet (PoE) systems. This device complies
to the power detection, level classification, and does the power regulation for the end system. For
the LM5070 specific information and functional description please refer to the datasheet.
General performance features of the application kit are:
The module is connected to the JumpStart Kits through two one row, right angle, SMD, RM2.54
connectors. The first one (P1) is a four pin connector that provides access to the PoE signals
coming from the Ethernet interface. The second one (P2) is a six pin connector that provides the
output power supply from the PoE module. The module makes a right-angle with the development
board.
The size of the POE_12V_JS board is 65.88 x 25 mm.
The following figure shows the placement of the POE_12V_JS board.
