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 syzaseegj, jegw-nmisezitj zkvzvriid pgwh qd tmrrtfqq TkK rgavfa (93 F tnq.) mws llnlrgbhg jhievrn ecdiemrby.
