electrical isolation per
802.3 requirements
Simplify implementation of
full PoE solution
Board real estate savings
Reduce board layout issues
Integrate new and existing
technologies into a single
connector unit
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
802.3af compliant
Auto and Enhanced mode
capable
Press-fit configuration
Ease of routing on
customer PCB
Signal integrity benefits

■
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
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

How Does PoE RJ45 Work?
■
■
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
Embedded inside each
RJ45 is the Silicon Power
PD64012 chip
Each RJ45 is a 12 port PoE
system, communicating
