These options allow the series to conduct accurate jitter tolerance measurements on devices with up to four channels such as multi-channel CPU boards, PC boards and optical devices, forming interconnects in routers, servers and super computers.

Low-Jitter, Spread-Spectrum Clock Modulators Reduce EMI in Large-Format LCD Panels

September 25, 2007 7:59 am | Product Releases | Comments

Maxim introduced its DS1081L/DS1083L 16 MHz to 134 MHz, center spread-spectrum clock modulators. These modulators use an integrated phase-locked loop (PLL) to dither the clock output around its center frequency at a user-selectable magnitude from 0 (disabled) to ±2.0 percent, thus reducing peak EMI at fundamental and harmonic frequencies. This EMI reduction is accomplished without changing clock rise/fall times or adding the space, weight, design time

Power Transistors Offer Enhanced Thermal Stability

September 25, 2007 7:48 am | Product Releases | Comments

Allegro announced a series of Darlington transistors for audio amplifiers. With a high safe operating area, (SOA) and low thermal resistance derived from a new thinner-die technology, the STD Series achieves high power performance in a common small package, the TO-3P. This series of parts is targeted at the home and professional audio amplifier markets.

Four-channel LIN Transceiver

September 25, 2007 7:42 am | Product Releases | Comments

Melexis introduced a four-channel LIN transceiver IC. It combines four LIN transceivers on one die and enables the development of simpler and more cost effective multi-LIN network master modules. Integrated 1K LIN master termination resistors and decoupling diodes further reduce system costs. This four-channel LIN transceiver is produced in 0.8µ HV-CMOS technology and is based on the single channel transceiver TH8082.

Liquid Coolers Chill Out

September 25, 2007 7:41 am | by Jon Titus, Senior Technical Editor | Articles | Comments

Liquid cooling provides a convenient way to remove heat from electronic components, boards, and systems. Its efficiency exceeds that of moving air, and liquid-cooling equipment does not require air channels throughout an enclosure. Some engineers may think of liquid cooling and picture leaking pipes and damaged electronics. Fortunately, liquid cooling has moved from the prove-it-to-me stage to routine use in high-end computers and military-and-aerospace equipment. So, just think of liquid cooling as a reliable and efficient way to move heat from one place to another. The removed heat can travel some distance to a radiator that dissipates the heat into outdoor air, municipal water, seawater or even another cooling system.

Ultrasonic Rangefinders Feature Custom Beam Width

September 25, 2007 7:40 am | Product Releases | Comments

MaxBotix, Inc. announces its LV-MaxSonar sensor with a factory calibrated beam width, allowing precision beam angles. Five ultrasonic rangefinders in the line are calibrated to a specific beam width, allowing users to select the sensor that provides the beam width of choice. The sensor beam width is widest for the model EZ0 that is well suited for users needing a high sensitivity or a wide beam width. Each sensor, the EZ1, EZ2, EZ3 and EZ4, is progressively narrower.
