Manage flash memory in auto infotainment systems
Design How-To 11/29/2006 Post a comment
As the costs of NAND and NOR flash continue to fall, in-car infotainment systems are using storage in ways that no one thought possible only a few years ago. To succeed, these systems need flash file systems that can ensure data integrity, even when power failures or uncontrolled shutdowns occur.

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.

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.

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
