Vitesse Semiconductor Corporation (NASDAQ:VTSS), a leading provider of advanced IC solutions for Carrier and Enterprise networks, is again expanding its Carrier Ethernet portfolio with a new family of switch engines, Serval™. Complementing the previously announced Jaguar™, LynX™ and Caracal™ solutions for Carrier access, aggregation, and mobile applications, Serval is optimized for power and cost-sensitive applications at the network edge, delivering 75% lower power and 50% lower BOM cost than competitive options.

Serval is the industry’s only switch engine family to support MPLS/MPLS-TP LER and LSR and patented LTE-advanced-ready IEEE 1588v2, useable in both fiber and microwave applications. The family also offers the most complete Ethernet Operations, Administration & Maintenance (OAM) support, critical for businesses which typically receive Ethernet services spanning multiple service provider networks.

“Ethernet markets are growing quickly — we forecast double-digit CAGRs for both Ethernet microwave backhaul equipment and Ethernet Access Devices through 2015, based on the dual fundamental drivers of growing traffic levels, and operators’ migration from legacy TDM backbones to all-Ethernet access/aggregation networks,” stated Michael Howard, principal analyst, carrier networks, at Infonetics Research. “Vitesse designed Serval to be optimized for Ethernet-based access systems, which will enable manufacturers to produce equipment that will help service providers achieve the operations efficiencies they need as they migrate their access networks to Ethernet.”

Design In Advantages with Serval

Serval is ideal for fiber, microwave and millimeter-wave backhaul, as well as wireline network edge devices, because it uniquely offers full OAM in hardware, including the Maintenance Entity End Points (MEPs) defined in IEEE 802.ag as MEP-Up and MEP-Down. Such connectivity fault management is crucial for businesses which must often rely on various service providers for Ethernet access.

Serval delivers a Vitesse patented feature set for Transparent Clock support over Microwave networks, whereas the competition lags on implementing the same level of precision in Vitesse’s IEEE1588v2 solution.

Serval extends beyond simple priority queuing, and includes hierarchical QoS, i.e. multi-stage scheduling, policing, and traffic shaping. It also provides the ability to separate subscriber types with per subscriber queuing, a unique capability of Serval compared to any other access Ethernet switch.

Serval is an Ethernet-optimized solution that meets all of the stringent Carrier network requirements and delivers twice the switching bandwidth at half the power consumed by a comparable NPU-based solution. In contrast, other solutions carry the high power and cost penalty of legacy TDM support. Additionally, they lack advanced Carrier Ethernet network requirements such as precision IEEE 1588v2 timing, the essential precision timing protocol required for operating mobile and edge networks.

Serval delivers the superior network timing and architectural advantages pivotal to successful deployments of small cell, mobile backhaul and network access equipment, such as Ethernet Access Devices (EAD) and Network Interface Devices (NID).

“Power is one of the highest OPEX considerations in many emerging regional networks, such as China and India. Compared to competitive ASSP and NPU-based solutions which range from 6-15W, Serval delivers the industry’s richest Carrier feature set for access-edge applications at less than 3W,” said Uday Mudoi, director of product marketing at Vitesse. “With Carriers trending towards small micro and pico cells to add network capacity, Serval is ideal for this burgeoning application. Additionally, with its industrial temperature range support, Serval enables a variety of outdoor and fanless designs, such as microwave backhaul enclosures and 1U Ethernet access device systems.”

Availability and Samples

Samples of the VSC7418 are available this month. More information about Serval can be found at: www.vitesse.com/products/product.php?number=VSC7418.

XP Power today announced the EMH250 and EMH350 series of highly efficient single output 250 Watt and 350 Watt AC-DC power supplies. Meeting the IT equipment safety specifications of UL/TUV/EN 60950-1 and the stringent medical safety standards of UL/TUV/EN 60601-1 the EMH series suit a broad range of information technology, industrial, medical equipment and surgical life support applications. All models are also BF rated.

Both the EMH250 250 W and the EMH350 350 W series have an extra wide input range of 80-275 VAC and are available in four output models covering the nominal voltages of + 12, + 18, + 24 or + 48 VDC. A trim function allows adjustment of the output voltage to within +/- 10% of stated nominal. A +12 VDC / 0.6 A fan supply is also provided across the range. In addition, the EMH350 series includes a +5 VDC / 2.0 A standby supply. Unlike many competitor models, full power is available from low input voltages of 90 VAC and the unit does not derate until +50 degrees C operating temperature. Measuring just 76.2 127 x 36.3 mm (3 x 5 x 1.43 inches), these industry standard format units require only 12 CFM of forced airflow in order to deliver the full output power. An optional top mounted fan is available across the range, and the EMH350 has the additional option of a variable speed fan that is dependent on the unit’s operating temperature.

The EMH350 series is also available with an optional ORing diode circuit that allows for current sharing in N+1 redundancy configurations. This series provides customers with the choice of either analogue or digital control options. The analogue signals provide Power Fail, Inhibit and Current Share. Digital signals and controls are accessible using PMBus compatible commands.  The EMH series is available from Farnell, Newark and element14 approved regional distributors, or direct from XP Power and come with a 3 year warranty.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced a worldwideseries of technical training seminars—beginning in January—that will show designers how to easily adapt to changing product requirements by migrating a real-world application from 8, to 16, to 32-bit PIC^® microcontrollers (MCUs).  These one-day classes will teach engineers how to migrate the application using one set of tools and with minimal code changes; demonstrating how they can save both time and money through reuse.  The seminars will utilize Microchip’s free software tools and the “One PIC MCU Platform Demo Board,” which is bundled with the PICkit™ 3 programmer and is available exclusively to attendees.

Many designers need to quickly expand product feature sets, or create a broad range of products at the outset, and they would prefer to save time and money by maintaining a common code base.  However, feature-set expansions often force designers to move to a new microcontroller that requires different tools.  Microchip’s free MPLAB^® X integrated development environment (IDE) enables designers to easily migrate code among all of the more than 800 8-bit, 16-bit and 32-bit PIC MCUs.  This seminar series walks designers through the migration of a real-world application using a single IDE, while illustrating how to select the best MCU for each design’s unique requirements.  The example application will also feature the latest technologies for low power consumption, human interfaceand connectivity in embedded designs, as it progresses from an entry-level to a top-of-the-line end product.

“In this economy, everyone must do more with less; so controlling your embedded design costs while differentiating your products is essential,” said Ken Pye, Microchip’s vice president of Worldwide Applications Engineering.  “These seminars are packed with practical information and advice on how Microchip can help you reduce your development time, reuse your software and tools, and migrate your design up or down as requirements change.”
