NetCell Corp., based here, claims its TurboDisk chip can control up to five hard drives while providing better performance and data protection than RAID Level 5 controllers, at a lower cost.
Kontron pre-announces embedded/mobile PCIbus module Product News 11/20/2003 Post a comment Kontron is revealing a few tidbits about a new embedded computing module the company will dish up as an OEM "building block." When it hits dealer's shelves next year, Kontron claims the small form-factor product will herald a "new class" of embedded computers, with control boards housed in a secure module that can be combined with other technologies within larger systems.
The Military Technology Design Challenge Product News 11/14/2003 Post a comment Today's military spending is driving the procurement of sophisticated systems. This trend presents new challenges for EEs designing-in components and board-level products. System testing is paramount to maximizing mission success.
Differential signaling provides noise cancellation for backplane clocking News & Analysis 11/12/2003 Post a comment To distribute clock signals over the backplane, topologies include point-to-point, multidrop, and multipoint. Each solution has its benefits and shortcomings, writes this Texas Instruments' applications specialist. Multipoint LVDS offers good broadcast capabilities, but requires an understanding of the voltage swings and signaling patterns required.
Board makers may be on the block News & Analysis 11/11/2003 Post a comment The embedded-boards market is abuzz with speculation that Force Computers and Dy4 Systems Inc. had been placed on the trading block by parent Solectron Corp. While industry watchers suggest that the sale of board makers might not herald a period of contraction in the boards industry, Planet Analog magazine says, "Where would turn for cover art?"
Mux rolls for serial attached SCSI storage News & Analysis 11/10/2003 Post a comment PMC-Sierra Inc. has become one of the first chip makers to dive into the nascent market for the serial attached SCSI interface. The launch of its PM8380 QuadSMX 3G reflects a growing consensus around existing Fibre Channel storage networks and direct-attached SCSI markets, as opposed to still-emerging Ethernet-based storage. Rick Merritt has this report.
Mellanox rolls first 30 Gbit/s Infiniband switch Product News 11/10/2003 Post a comment In love with Interface components: This one goes faster than 30 Gbits/s. A startup called Mellanox Technologies is supporting Linux clusters and rolled out Monday (Nov. 10) its first Infiniband switch capable of handling 30 Gbit/second data transfers. The InfiniScale III is aimed at port aggregation and lowering cost per port for the high-speed, low latency interconnect. EE Times even had the price and delivery.
Parallel port transceiver features power-on protection feature Product News 11/10/2003 Post a comment STMicroelectronics' 74LVC161284TTR is a low-voltage, high-speed IEEE1284 transceiver. A "Z" version, the 74LVCZ161284ATTR is almost identical, but features an error-free power-up function as well. Each of these transceivers can replace the function of two previous-generation 74ACT1284 devices. Both parts support both IEEE1284-I and -II (level one and level two) bi-directional parallel communications between personal computers and peripherals.
Input Capacitor and Stability Considerations in EMI filters - Part 6 in the series News & Analysis 11/10/2003 Post a comment There are things we may do unintentionally at the input of the converter that can have a major impact on the performance of the EMI filter and the converter itself, writes National Semiconductor's Sanjaya Maniktala in this new installment of the series on EMI. If we don't know the rules, we can end up saturating our filter chokes and even inducing loop instability. Pick your capacitors carefully!
Serdes claims 10-Gbit backplane channels News & Analysis 11/4/2003 Post a comment Agere Systems has built a 90-nanometer serializer/deserializer chip that can deliver 12.5-Gbit/second throughput, giving designers a way to provide 10-Gbit channels across backplanes in networking-box architectures.
Fail-safe 40Mbits/s transceivers support Profibus, RS-485/RS-422 News & Analysis 11/4/2003 Post a comment Maxim's MAX3465-MAX3469, announced this week are fail-safe, 40Mbits/s Profibus transceivers. These devices are high-speed, differential-bus transceivers for RS-485 and RS-422 communications, and are designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards. From eeProductCenter's postings, here's the scoop.

D2Audio vies to redefine digital amplifiers News & Analysis 11/3/2003 Post a comment Two-year-old startup D2Audio Corp. is gambling that the growing popularity of home theater--surround-sound "stereos" with five or more output channels--will turn its digital amplifier modules into a cash cow. What drives module-maker D2Audio's business is the need for fast time-to-market. David Lammers interviewed company principals in Austin.
