Proper Layout and Component Selection Controls EMI
News & Analysis  
9/30/2003   Post a comment
Understanding the physics of voltage-regulator topologies is important when designing power systems for EMI and EMC compliance. In particular, the physical principles behind switching regulators (buck, boost, flyback, and SEPIC topologies) guide component choice, magnetics design, and PC board layout. Parasitic elements such as leakage inductance, ESR, and ESL are significant when optimizing circuit performance.

Cambridge Silicon Radio (CSR) and Cypress Semiconductor have jointly developed a less-than-$15 (total BOM) Bluetooth solution for off-the-shelf USB-enabled peripherals.
CAN controller chip tackles serial communications apps
News & Analysis  
9/25/2003   Post a comment
Microchip Technology's newest standalone controller-area network (CAN) device now offers the option to address serial communications challenges. The MCP2515 gives designers a CAN solution that provides faster data throughput and efficient data byte filtering, the company said. It also generates start-of-frame output and uses an SPI interface.
New PC Card Spec Rides Express, USB 2.0
News & Analysis  
9/19/2003   Post a comment
The final 1.0 specification for next-generation PC Cards was unveiled here at the Intel Developer Forum on Tuesday Sept 16. However, backers admit the thinner and faster cards will take time to catch on due to a lack of applications to drive the transition to a new slot and card form factor.
Pentek VIM-2 module provides transmit functions for soft radio
Product News  
9/18/2003   Post a comment
Pentek Inc.'s model 6228 VIM-2 (velocity interface mezzanine) module delivers high-performance transmit functions for software-radio systems, thanks in large part to its use of two new Texas Instruments DAC5686 wideband interpolating digital-to-analog converters with integrated upconverters and a Xilinx Virtex-II XC2V1000 or 3000 FPGA for custom programming, according to Pentek.
Texas Instruments supports 1.5V to 3.3V level translation with a 32-bit wide device
News & Analysis  
9/16/2003   Post a comment
Texas Instruments announced Tuesday (September 16) a 32-bit wide level translator. This device allows bi-directional level translation between 1.5V, 1.8V, 2.5V, and 3.3V logic levels. The AVCB324245 implements an interface between two systems that have dissimilar trigger and out voltages, while maintaining signal integrity and speed.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
