Where in the design cycle is it best to spec in a timing device, and why? Ramon Cerda, Vice President of Engineering , Crystek Corporation The short answer is; as soon as possible. Most, if not all timing devices should be treated as long lead-times items. If the crystal oscillator manufacturer does not have your particular frequency and/or specification requirement in stock, it can take many weeks before they can deliver the timing device.
How are you responding to the demand for low power/high efficiency devices in the emerging markets? Jeff Schnabel, VP of Marketing at CUI Inc : In order to address the growing global concerns regarding energy consumption in electronic equipment, the power supply industry has largely focused on improving the operating efficiency of ac-dc power supplies and dc-dc converters.
In the future, how will battery technology need to respond to the increased power demands of today’s advanced sensors? Technological advancements are creating a dynamic growth curve for sensors intended for use in remote areas where there is no connection to the power grid.
Question: What are the primary drivers for developing low power designs? Cost savings, movement to green, longer life for batteries? One of the most critical factors for component and board designers pursuing low power wireless designs is the overall power budget. By reducing the power demand of the radio, the designer can allocate more power to other things on the board, adding more features and capabilities, without having to go through a new cycle of development and testing.
Question: What type of innovation must take place to provide the ability to increase the efficiency of renewable energy while reducing its cost? In regards to how the renewable energy market can become a more profitable business entity, we see it from a larger perspective than innovation at just the component, board or system level.
Question : How can effective use of software design tools improve the product development cycle and help the designer engineer get it right the first time? By: Frank Liu, Communications and Electronics Industry Marketing, MathWorks Successful product development teams are made up of engineers who can span multiple application domains and multiple design phases.
Question : How can today’s LEDs be improved to provide better performance (brighter, longer life) while at the same time lowering energy consumption? By: Brian Witzen Sr. Field Technical Manager Sharp In commercial buildings, lighting accounts for a substantial portion of the energy budget and total energy cost.
Question: What types of improvements need to be made in network technology/architecture that can provide improved performance and capabilities in military applications? By: Mukesh Kumar, Multicore DSP Marketing Manager, Texas Instruments With the Department of Defense taking a more net-centric approach to communications, the focus is on the implementation of the Global Information Grid (GIG) project.
The Question: "The constant movement of data increases a company’s exposure to the risk of data loss. What type of solutions can help cost effectively identify and protect an organization’s critical data from internal and external threats?" By Will Aguilar, Director, Product Management for Wireless, Enterasys Networks The growth of mobile devices in the enterprise has been explosive and drives end-users’ expectation they will be able to access business services anywhere, anytime in the office, campus, or remotely.
Q: How can semiconductor packaging help support these new advanced technologies so that gains at the wafer level are not lost at the system level? By Ralph Ebbutt, Tektronix Component Solutions The advancement of semiconductor process nodes and the demand for miniaturization creates multiple challenges for the packaging industry.
With all the new features consumers want in the cars they buy today, the number of automotive electronics, which require complex semiconductors, continues to increase. Q: “How do designers stay within their power budget and still remain competitive?” By Michael Haight, Freescale “I want it all” is often the desire for the car buyer.
The future holds RFID Applications that go far beyond mere bar coding. The world will be a different place once readers and RFID tags are everywhere. Q: “What are some of the untapped applications for RFID that we may see in the foreseeable future?” By Victor Vega, Alien Technology UHF RFID has matured to a point where “it just works.
Multiple antenna technology enables high capacity and high data rates. Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.
Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? William J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.
It wasn’t all that long ago that Multiple-Input Multiple-Output (MIMO) technology first captured the cellular industry’s attention by promising higher data rates for a single user using two or four streams of data transmitted (and received) with multiple antennas.
Have the rapid technological changes of the past decade negatively or positively impacted the timing solutions market place?July 25, 2010 8:08 am | by Jim Holbrook, General Manager, Networking and Communications Timing at IDT | Articles | Comments
One of the most significant technological changes that has occurred in the past decade has been the shift from parallel to serial busses for high-speed system I/O and also for chip-to-chip interconnect. Examples of this trend are: •PCI Express for PCs, servers and increasingly in networking and communications platforms •Serial RapidIO for wireless base stations •Infiniband and Fibre Channel for data centers •VITA 46.
WiMAX and LTE continue to pose many unanswered questions. Q: What common or overlapping technologies do WiMAX and LTE have in common and will they ever converge for certain applications? By Joe Cozzarelli, Senior Director Broadband RF Products and Glenn Eswein, Director of Product Marketing, Broadband RF Business After three years of deliberation, the IEEE802.
The path to achieving energy efficiency is ridden with obstacles. Q: If we continue to increase the power efficiency of a product, are we approaching the point of diminishing returns? Will it eventually detrimentally impact the cost of the product? Doug Bailey, VP marketing, Power Integrations This is an interesting question.
After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.
