Commentary: The benefits of standardization in packaging Product News 10/26/2003 Post a comment There are many ways to illustrate the benefits of standardization for suppliers, distributors, manufacturers, and ultimately, the end consumer. Standardization of the USB port on the PC, for example, has made the addition of peripherals relatively simple and inexpensive. The more you standardize, the more you drive down costs, insist these competitors in an opinion piece that originally appeared in EBN.
Where standard logic was in 2001 Product News 10/26/2003 Post a comment Standard logic in 2000 maintained a solid presence in an increasingly specialized semiconductor market. The general-purpose, or "glue logic," nature of standard logic continued to help it stay competitive with ASICs, systems-on-a-chip, and other integrated solutions. EBN said the market was strong.
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.
Power-over-Ethernet hookup eased Product News 10/26/2003 Post a comment Linear Technology's LTC4257 interface controller is the company's first power-over-Ethernet device made specifically to meet the powered device (PD) requirements of IEEE's 802.3af specification.
Maxim switch powers up to eight USB ports Product News 10/26/2003 Post a comment Maxim's MAX1562, MAX1562H and MAX-1563 current-limited switches power up to eight Universal Serial Bus ports. These 3- and 4-amp devices offer such features as autoreset and fault blanking for USB applications in notebook and desktop computers.
PowerQUICC III Adds Security Engine Product News 10/25/2003 Post a comment Motorola is unveiling the new MPC8555 PowerQUICC III processor with integrated security at the Network Processors Conference West in San Jose, California and at the Smart Networks Developer Forum (SNDF) in Taipei, Taiwan, and Qingdao, China.
VIA Finds a Way to Trim Processor Size, Add Security Features Product News 10/24/2003 Post a comment Made in a 130nm process and available at speeds of 533MHz, 800MHz and 1GHz, the Eden-N is almost without question Via's best processor yet. It features the very small nanoBGA package, which measures just 15mm x 15mm. By comparison, Intel's Pentium M CPU measures in at 35mm x 35mm
Maxim announces 3841crosspoint switch Product News 10/24/2003 Post a comment The MAX3841 is ideal for high-speed serial-data loopback, redundancy and switching for serial OC-192 and 10-Gigabit Ethernet applications or other applications up to 12.5 Gbits/s. Jon Gabay gives this assessment.
DRAM vendors slot DDR3 for 2006 debut News & Analysis 10/24/2003 Post a comment
With DDR2 SDRAM just getting ready to crack the market, memory makers last week confirmed that the architecture's follow-on, DDR3, will debut in 2006.
At a JEDEX conference here, the JEDEC Solid State Technology Association said a feature set for the DDR3 standard will be defined in 2004.
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.

"Shoot-Through" in Synchronous Buck Converters News & Analysis 10/23/2003 Post a comment The synchronous buck circuit is in widespread use to provide "point-of-use" high-current, low-voltage power for CPUs, chip sets, peripherals, etc. In the synchronous buck converter, the power stage has a "high-side" MOSFET to charge the inductor, and a "low-side" MOSFET that replaces a conventional buck regulator's "catch diode" to provide a low-loss recalculation path for the inductor current. Shoot-through is defined as the condition when both MOSFETs are either fully or partially turned on.
