Transceivers deliver long range at low cost Product News 5/20/2004 Post a comment AeroComm has introduced the 900MHz AC4490-1W transceiver for the growing demand for increased range among local-area industrial communication applications. It provides one watt of output allowing for data transmissions of up to 115.2 Kbps across 20 miles line-of-sight.
Hard disk drive read channels " a must for perpendicular recording News & Analysis 5/20/2004 Post a comment Data recorded on magnetic disk platters follow a complex analog path from being initially 'read' to final digitization in a read channel. In this article from the May Planet Analog magazine, an Agere Systems engineer describes the read channel chain used in the coming generation of hard disk drives using perpendicular recording.
Analog switches beat bus switches in ultra-portable and consumer USB applications News & Analysis 5/20/2004 Post a comment The notebooks/PCs continued to incorporate the switches for multiplexing applications that includes overlaying graphics onto video (Picture-In-Picture), switching of MPEG data streams (after the serial-parallel conversion) and then the multiplexing of the RGB data between different monitor sources (TV, LCD, PC monitor) on video accelerator cards. In this tutorial, a Fairchild apps engineer offers insights into video switch design specs.
Compact PCI runs FPGA and "soft" processor development tool Product News 5/20/2004 Post a comment Pender, based in Germany, expands its product offerings for FPGAs and its 32-bit LEON open source VHDL processor. The new GR-CPCI-XC2V board provides a Xilinx large capacity FPGA and is implemented in a Compact PCI format with all the necessary interfaces for LEON development. The FPGA, programmed to execute LEON tasks, can offer a performance advantage to a variety of embedded tasks.
TI ponders best routes to next-gen handset feature integration News & Analysis 5/19/2004 Post a comment Texas Instruments Inc. has some choices to make on how to integrate new features into the cell phone. Already, TI is bringing functions such as voice-over-Internet Protocol (VoIP) and video decompression from its digital consumer operations to its cell phone division. After Bluetooth, what else do you put in? David Lammers has this report.
Epson demonstrates 40-inch OLED display News & Analysis 5/19/2004 Post a comment Seiko Epson Corp. has developed a 40-inch diagonal organic light-emitting diode (OLED) display prototype and announced that it will offer polymer-based OLED products beginning in 2007, perhaps including a 40-inch OLED TV.
MCM converters plug in to flexible prototyping Product News 5/19/2004 Post a comment Streamlining the prototyping process for intermediate-bus architecture and point-of-load (IBA/POL) designs, Vishay Intertechnology now offers designers plug-in versions of all devices in its FunctionPAK family of fully integrated DC/DC converters. The 8-pin plug-in multichip modules (MCMs) are complete synchronized buck or boost converters with programmable topology and will be particularly attractive to engineering labs with limited assembly equipment.
4-phase controller touts benchmark performance News & Analysis 5/19/2004 Post a comment Intersil says its Endura ISL6564, for embedded computing through point-of-load applications, is the most advanced four-phase synchronous-buck PWM controller available. The company touts 6-bit VID (voltage identification) for delivering the industry's most granular output range (down to 0.525 V), and tightest voltage regulation.
Blog Doing Math in FPGAs Tom Burke 16 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
