AUSTIN, Texas, Nov 09, 2009 (BUSINESS WIRE) -- Silicon
Laboratories Inc. (NASDAQ: SLAB) and Vitesse Semiconductor
Corporation (Pink Sheets: VTSS.PK) today announced the availability of
multiple reference designs to enable easy upgrades for Vitesse-based
Gigabit Ethernet switches to support the recently ratified IEEE 802.3at
Power over Ethernet (PoE+) standard. Two new reference designs combine
Silicon Laboratories' highly integrated, energy-efficient PoE Power
Sourcing Equipment (PSE) controllers and the Vitesse E-StaX(TM) and SparX(TM)
Gigabit Ethernet switching chipsets for 24-port stackable and 5- to
24-port workgroup and desktop switches, respectively.
The first joint design is a PSE daughtercard for E-StaX(TM) and SparX-II(TM)
switches. The plug-in daughtercard features an isolated I2C interface,
self-contained operation from an isolated PoE supply (54 V nom.) and
efficient thermal profiling. The design supports 24 ports at up to 30 W
each with full IEEE 802.3at compliance. Multiple daughtercards can
interoperate on a single I2C host interface for high port count
scalability. Switch host software integration and an independent PoE
power supply enable a single switch motherboard design appropriate for
PoE and non-PoE SKUs.
The second design is a single motherboard implementation for the
SparX-G8e(TM) switch. Supporting eight ports of PoE (15.4 W) or PoE+ (30 W)
capability and Vitesse's Web-based configuration and power management
GUI, this complete PoE-enabled switch is intended for applications such
as desktop switches, VoIP telephony, wireless access points, industrial
networking, video surveillance and security systems.
Both reference designs include schematics, bill of materials, and
comprehensive PCB layout files for fastest time-to-market and design
success. Silicon Labs' Power Manager Software Development Kit (SDK) is
available to enable system developers to quickly develop highly
differentiated PSE systems with sophisticated power management features
to minimize power supply costs and maximize energy efficiency.
Based on Silicon Labs' Si345x PoE+ PSE controller family, designers can
take advantage of real-time power measurement capabilities. The Si345x
incorporates high-precision current and voltage measurement capability
to monitor the power consumed by each port, enabling systems to maintain
tighter control of power allocation, which translates to smaller power
supplies and lower supply overhead and gives system administrators
visibility into how much power is allocated to and consumed by each port
in their network. Link layer discovery protocol (LLDP) power management
algorithms are implemented at the system level, enabling dynamic power
allocation.
Vitesse's E-StaX products feature its VStaX(TM) cabling technology, a
scalable high-speed 24+4 port configuration, a performance-driven
architecture and a rich integrated feature set to deliver low-cost
Gigabit Ethernet for OEM and ODM customers. The SparX unmanaged and
smart Web-managed switches eliminate the need for external processing
and memory found in fully managed switches, allowing developers to
deliver a smart switch with advanced Layer-2 capabilities at a fraction
of the cost for a fully managed switch. SparX switches also include
Vitesse's award-winning EcoEthernet(TM) technology that delivers green
savings equivalent to more than 400 mW per port. Both product families
are ideal for Carrier Ethernet applications as they support Synchronous
Ethernet with SSM according to ITU-G.8264/Y.1362 and offer fast
protection switching with switching times significantly below the 50 ms
telecom requirement.
