PoE Product Features
■Integrated Silicon PoE
12-port controller
■802.3af compliant
■Auto and Enhanced mode
capable
■Footprint
■Press-fit configuration
■Ease of routing on
customer PCB
■Pin Assignments
■Signal integrity benefits
vs. standard footprint
■Three options in same
footprint:
■Integrated Magnetics Only
■Integrated Magnetics,
Enabled PoE
■Integrated Magnetics,
Integrated PoE
■2250Vdc / 1500Vac
electrical isolation per
802.3 requirements
Customer Benefits:
■Simplify implementation of
full PoE solution
■Board real estate savings
■Reduce board layout issues
■Integrate new and existing
technologies into a single
connector unit
Why Integrate the PoE
Circuitry into the RJ?
■Single package (PoE, LED’s,
Magnetics, Heat Sink)
■Identical footprint for both
Integrated PoE/Enabled and
non-PoE
■Single design, single
motherboard can be used
for both PoE and non-PoE
■Same design can migrate
between switches (including
blades and fixed)
■Delivered fully tested and
qualified, no need to bother
with complicated PoE
testing
■Reduced layer count/
Reduces cost of motherboard
■No PoE daughterboards
■Isolated PoE voltage
provided directly from the
power supply
■All per port components
embedded in RJ
■Eliminates issues of voltage
isolation on motherboard
■Reduces EMI risks
PoE Controller Features
■Power supplied over data
contacts 1 & 2 and 3 & 6
■I2C Capability
■PoE chip provides power
and command/control
circuitry from motherboard
power plane/bus
■Provides isolation between
earth/building and signal
ground
■Real time control of
overload, underload, short
circuits and under voltage
states
■0.5A current carrying
capacity
■Full AC disconnect and
classification
■80V tolerant, surge
protected system
■Registers for MIB 8 support
and parameters adjustment
■Single voltage feeding
(44 – 57VDC)
■Designed to support legacy
capacitor detection
How Does PoE RJ45 Work?
■Embedded inside each
RJ45 is the Silicon Power
PD64012 chip
■Each RJ45 is a 12 port PoE
system, communicating
with each other to create a
system of up to 48 ports
■The Host CPU controls the
system via I2C
■Two main operating modes:
Automatic/Enhanced Mode
to match system customiza-
tion requirements
