AUSTIN, Texas--(BUSINESS WIRE)--Nov. 5, 2007--Silicon Laboratories
Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today announced the industry's first dual-function,
single-port Power over Ethernet (PoE) controller with an integrated
dc-dc controller for power sourcing equipment (PSE). By combining
these two functions, the Si3460 dramatically simplifies development
efforts, reduces system costs and eliminates specification compliance
challenges for designers of a broad range of emerging PoE applications
such as in home gateways, set-top boxes, cable modems, DSL modems and
Voice over IP systems.
Unlike competing single-port solutions providing only a PSE
interface, the Si3460 integrates a dc-dc digital power controller to
cost effectively generate a negative 48V PSE supply, ensuring safety
extra low voltage (SELV) compatibility with legacy telephony ports
within the system. The Si3460 reduces the total PSE solution cost to
less than US$2.00 and preserves the use of low-cost, 12V power supply
adapters and typical point-of-load (POL) dc-dc converters. The
Si3460-EVB reference design, which includes all the recommended
external components for a complete single-port PSE design, also
provides IEEE 802.3af-compliant detection, classification and
disconnect functionality.
The Si3460 controller provides extensive protection such as inrush
current control, input under voltage lockout (UVLO), short circuit
protection and current limiting to ensure robust, fail-safe operation
during all operating conditions. The Si3460 also supports Fast (10/100
Mbps) and Gigabit Ethernet endpoints and midspans and is pin
configurable to supply maximum power (15.4W, Class 0) PSEs, or limit
power to IEEE class levels one through three.
"The Si3460 uniquely solves the two main challenges facing PSE
systems designers: implementing a fully compliant IEEE 802.3 PSE
interface and easily and safely generating the negative 48V PSE power
supply from an existing low-voltage supply," said Dave Bresemann, vice
president of Silicon Labs. "In combination with the Si3400/01
controller for PDs, Silicon Labs provides end-to-end solutions for
PoE."
Pricing and Availability
The Si3460 is sampling now with volume production in January 2008.
The device is packaged in a RoHS compliant, Pb-free, 3 x 3mm QFN
package. Pricing starts at $1.05 each in quantities of 10K units. The
comprehensive Si3460-EVB reference design kit is available now for
$95.00.
