Designers are taking back the JTAG test bus! Blog 10/30/2003 Post a comment It's not just for test anymore: Recent extensions to JTAG not only enhance its test coverage, but also make it useful for design as well, says this National Semiconductor technologist. Suppliers of CPLD's and FPGA's were quick to support IEEE 1532 standard for Boundary-Scan-based In-System-Configuration of programmable devices. Now designers have a way to develop flexible systems where functionality can be adapted to a specific customer or application, he says.
Pericom announces asynchronous mode support for PCI-to-PCI bridges News & Analysis 10/29/2003 Post a comment Asynchronous mode allows users to run the secondary bus at a frequency that is not derived from the primary bus, thus providing far greater support for next generation PCI bus designs. Asynchronous mode support is significant as customers engineer newer faster designs that need to merge with slower legacy devices, Pericom says.
LVDS serializer touts dc balance feature Product News 10/29/2003 Post a comment Maxim Integrated Products' MAX9209 21-bit low-voltage differential-signaling serializer offers users a programmable dc balance, which allows isolation between the serializer and deserializer by using ac coupling. The device serializes 21 bits of LVTTL/LVCMOS parallel inputs to three LVDS outputs

DSP development platforms support real-time COTS Product News 10/28/2003 Post a comment Pentek has been in the habit of supplying cost-effective, standard system boards for high-performance, multi-channel embedded applications. But a strategic alliance with DSPCon enables the company to target fully-integrated, cots-based solutions. TRS off-the-shelf products eliminate the time and risk associated with new technology system development, the company says.
TI claims First Demo of PCI Express-to-PCI Bridge Product News 10/26/2003 Post a comment PCI Express is a dual-simplex, point-to-point serial differential low-voltage interconnect that will consolidate all application requirements for use by multiple market segments. PCI Express architecture will be a high-performance, highly flexible, scalable, reliable, stable and cost-effective general-purpose I/O architecture that will seamlessly complement existing PCI buses and transition the market over the next several years, allowing system and communication designers to use new topologies.
Notebook card fits USB 2.0, Firewire Product News 10/26/2003 Post a comment Orange Micro's OrangeCombo card for PC and Macintosh laptops has two USB 2.0 ports, a six-pin Firewire port and a four-pin Fire-wire port, all of which can run simultaneously.
Bus switch chip families aim for mixed-signal apps Product News 10/26/2003 Post a comment Texas Instruments Inc. says it has designed its CB3T, CB3Q and CBT-C bus switch chip families to meet the needs of system designers who face the challenge of supporting mixed-mode signal operation and need bus interface devices that provide voltage translation.
TI's transceivers satisfy TIA/EIA-485 Product News 10/24/2003 Post a comment Texas Instruments' SN65HVD1176 and SN75HVD1176 Profibus transceivers have been designed to provide improved output transition skew of less than 1 nanosecond (0.2 ns typical), giving system designers the ability to tighten up the total timing budget of their networked applications.
USB Data-Acq Attack News & Analysis 10/22/2003 Post a comment Legacy PC users may miss them, but most new PCs are devoid of parallel printer ports, and in many cases even the venerable serial I/O connector. Universal Serial Bus is taking center stage, as Centronix and RS-232 conventions fade into PC history.
Backplanes get reference designs News & Analysis 10/22/2003 Post a comment As the speed of backplane interconnection systems increases, whether for networking, server or storage applications, connector manufacturers are finding it necessary to collaborate with silicon vendors on backplane reference platforms to validate their high-speed solutions. It's getting common today to find reference platforms that demonstrate the performance of a high-speed interconnect, backplane and transceiver products in real-life environments that show the entire system-level performance.
Lost Link Bandwidth " How to get it Back News & Analysis 10/21/2003 Post a comment Link bandwidth can be a slippery animal, writes TriCN's John Ellis, in this article adopted from the recent Comms Design Conferent. Without careful thought on the front end of the design, he says, attenuation, reflections and system noise can quickly turn a planned 10 Gbits/s link into mush. A thoughtful approach to the entire signal path " chips to leadframes, leadframes to boards, boards to connectors, connectors to backplanes, and back again " and inclusion of well-chosen equalization techniq
Quellan preps noise canceler chip News & Analysis 10/20/2003 Post a comment Quellan Inc. will announce an analog noise-cancellation chip that supports 5- and 6.25-Gbit/second backplane designs at the International Microelectronics and Packaging Society's IMAPS 2003 symposium. Quellan's Nx600 noise-canceling receiver extends the "speed reach" of gigabit backplanes, the company claims. Steve Ohr has this repoty.
Multiple vendors smarten up their hot-swap protection ICs News & Analysis 10/15/2003 Post a comment Hot-swap controller chips are coming to market in greater numbers and packed with more smarts. They've quickly evolved from discrete circuits into highly integrated chips, equipped with thermal sensing, that are proactive in maintaining power and board stability during transient events, as when a card is inserted into a live backplane. Concurrent with EE Times' InFocus report on backplane power management, Vince Biancomano has this survey on new controllers.
Not a short list: High-speed backplane design considerations News & Analysis 10/14/2003 Post a comment A new generation of backplanes is emerging that achieve 5 to 10 GBits/s signal speeds, and even higher speeds are on the horizon. In this paper, adopted from the recent Communications Design Conference, a Flextronics engineer - an old hand at high-speed board design - discusses the design tradeoffs, materials, connectors, transmission line and signal integrity effects necessary to finding workable board and backplane solutions.
Wireless data card carries connections Teardown 10/6/2003 Post a comment Raising the bar on "always connected," the Nokia D211 wireless network card keeps notebook PC users on the air via low-cost 802.11b or pricier wireless carrier data plans, all at the flick of a software switch.
