Single-Port Si3462 PoE+ Controller Enables Easy, Cost-Effective,
Plug-and-Play Power Sourcing Equipment Solution
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced a single-port Power
over Ethernet (PoE) controller that brings economical "plug-and-play"
simplicity to embedded power sourcing equipment (PSE) designs. The new
Si3462 controller eases the development of PSE endpoints such as
residential gateways, set-top boxes, fiber-optic media converters, and
surveillance and security systems that connect to a wide variety of
powered devices including VoIP phones, security cameras, keypads,
network attached storage and WiFi access points.
Powered devices (PD) continue to proliferate in small office/home office
(SOHO) and small-to-medium business (SMB) markets, driving the need for
easy-to-use single-port embedded PoE/PoE+ PSE solutions to enable these
end devices. With the rising popularity of the higher power IEEE 802.3at
PoE+ standard and the need to support PD applications that consume up to
30 watts, developers require PSE controllers that offer flexible power
measurement and monitoring capabilities, standards-compliance and no
interoperability hassles.
The Si3462 controller is a complete, cost-effective single-port PoE and
PoE+ PSE solution. When deployed with the new Classification Optional
Mode, the Si3462 eliminates the need for up to 10 discrete components,
reducing the total BOM cost for embedded PSE to as little as $1.60
(USD). In this mode, the Si3462 controller determines when a valid PD is
connected at the other end of the cable and immediately applies a
predetermined amount of power. This mode optimizes cost and simplicity
for applications that do not require classification such as proprietary
systems operating with a fixed set of PDs.
The Si3462 controller's innovative architecture eliminates the need for
a separate MCU and related software, simplifying overall system
integration, mitigating software development costs and risks, and
speeding time to market. The Si3462 device's detection, classification,
power-up, fault monitoring, protection and disconnect processes all run
according to hardware pin configurations without the assistance of a
host processor or MCU. The Si3462 continuously monitors the power
delivered to PDs, ensuring that each PD is operating safely and within
all IEEE-required PoE/PoE+ specifications.
"The new Si3462 controller makes the adoption of PoE+ in embedded PSE
systems easier and more cost-effective than ever, while freeing
developers from the standards compliance risks and complexities
associated with other PSE solutions," said Jim Judkins, product line
director for Access products at Silicon Labs. "PSE can now be deployed
with plug-and-play simplicity, eliminating the need for host MCUs and
high-overhead software."
The Si3462 controller provides a variety of easy-to-use, pin-selectable
operating modes that enable the flexible use of the device in both PSE
endpoint and midspan applications. Although primarily designed for PSE
endpoint products, the Si3462 controller also easily supports midspan
power injectors widely used in small business and enterprise local area
networks. Midspans enable a remote PD to be powered by a legacy Ethernet
switch without PSE capability by inserting the midspan between the PSE
endpoint and the PD.
Pricing and Availability
The Si3462 controller is available now in production quantities in a
tiny 3 mm x 3 mm QFN package. The Si3462 is priced at $0.95 (USD) in
10,000-unit quantities. To help developers reduce development time and
cost, Silicon Labs offers the Si3462-EVB evaluation kit, a comprehensive
turnkey design that enables a cost-effective drop-in implementation of a
single PoE+ PSE port. The Si3462-EVB is available now for $95 (USD). For
