MAG45 with PoE Controller
RJ45 + PoE Magnetics +
Silicon Power Controller
Chip
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
