Media SoC design for reduced power consumption Design How-To 11/24/2006 Post a comment To achieve high integration and simultaneously reduce the overall system power consumption, the media SoC -- for both portables and AC powered devices -- needs to be designed with architectures that are "power conscious" which use design techniques to reduce the overall gate count and power consumption while efficiently handling data transactions to minimize inefficient, power consuming interactions with external memory.
Extreme automotive environment challenges sensor design Design How-To 11/22/2006 Post a comment Regardless of the specific application, most automotive sensor modules share a common high-level architecture and a set of stringent requirements that make for a challenging design under the high temperatures, noise, and vibration found in a car. Here are some design hints to deal with these hurdles.
Analyst: PortalPlayer nabs Apple iPhone design win News & Analysis 11/21/2006 Post a comment PortalPlayer, the media processor company that famously lost a key socket in the next-generation iPod nano earlier this year, has secured an applications processor design win in the forthcoming iPhone from Apple Computer, according to a Wall Street research analyst.
Sony, NXP plan JV for contactless smart card chip News & Analysis 11/20/2006 Post a comment NXP Semiconductors signed a memorandum of understanding with Sony, establishing a joint venture to create a secure chip for contactless smart card applications in mobile phones. The companies aim to establish the venture by the middle of 2007.
21-bit LVDS deserializer reduces EMI, cost for displays Product News 11/17/2006 Post a comment Check out Maxim's latest member of its high-speed LVDS SerDes family, a hot-swappable, 21-bit DC-balanced LVDS deserializer with programmable spread spectrum. The MAX9254 spreads output clock and data over a specified ±2% or ±4% range to reduce EMI. By reducing the number of wires/traces from 22 to 8, the MAX9254 simplifies design, saves space, and diminishes the cost of system interconnects, such as cables and backplanes.
BGA partitioning, PCB layout are crucial to video system design Design How-To 11/17/2006 Post a comment Image processing operations are normally noise sensitive to start with. If signals are not clean, they cannot generate clear images of the desired subject. High-pin count, fine-pitch BGAs ranging upwards of 1,052 pins are increasingly being used for video systems design. This means routing signals becomes more difficult. Precise BGA partitioning on a PCB is a crucial design aspect to minimize or eliminate crosstalk and noise, and help resolve manufacturing issues.
1-Gbits/s LVDS chipset rolls with embedded clock architecture Product News 11/14/2006 Post a comment Check out this LVDS SerDes chipset from National Semiconductor. It can serialize 24 bits of data over a single differential pair at a bandwidth speed of 1.03-Gbits/s. And it features an embedded clock architecture that eliminates the need for a second oscillator at the receiver.
Four-channel transceiver module samples for InfiniBand applications Product News 11/14/2006 Post a comment Zarlink Semiconductor is sampling a quad small form-factor pluggable (QSFP) transceiver module that it says provides InfiniBand equipment manufacturers with edge and board density savings of more than 60% while slashing power consumption to 250-mW per transceiver channel. At 5-Gbits/s on each of the eight fibers, the Zarlink module is said to offer the densest, pluggable transceiver bandwidth on the market.
Bartronics India plans chip plant in Hyderabad News & Analysis 11/10/2006 Post a comment Bartonics India is to set up a manufacturing plant in Hyderabad in southern India to make chips for smart cards in a pact with Watchdata Technologies, according to a report. The plant is expected to cost $40 million to $50 million and open in 2008.
Zarlink to make four-channel Infiniband push News & Analysis 11/9/2006 Post a comment Zarlink Semiconductor has placed a four-channel Infiniband interface into the Quad Small Form-factor Pluggable (QSFP) transceiver package supported by 21 component and system companies. The company will demonstrate 10- and 20-Gbit/sec versions of its module at next week's Supercomputing 2006 show in Tampa, Fla.

DSP video processing without DSP programming, via open source APIs Design How-To 11/3/2006 1 comment GStreamer, a popular open source Linux multimedia framework that has become a standard in digital video development, can now be used to access the video encoding and decoding capabilities of a DSP, without any need to learn the proprietary DSP programming language. This approach makes it easy to integrate DSP video processing with other requirements of the application that are typically performed on a GPP core. The multimedia framework handles the integration task by stitching together the vario
