Suitable for applications requiring a single point-to-point or a multi-point communications link, the Model 4152/4153 ST Fiber-to-Multi-Point RS485/422/232 Interface Converter from Electro Standards Laboratories has typical operating speeds up to 1.5 Mbps for RS232 to fiber conversion and up to 5 Mbps for RS485/422 to fiber conversion.
Here are a couple of articles on efficiency in flywheel and electro-optical systems from Douglas Electrical Components and Wavelength Electronics.
Here are some essays on design for you on Power over Ethernet (PoE), Transformer Basics, and info on the REACH chemical regulations.
This Month's Question: What do you think is the chief factor preventing the mainstream adoption of solid-state lighting?
One of the most difficult electronics design challenge is to track down and eliminate electromagnetic interference (EMI). Switching regulators, a common source of EMI, continue growing in usage due to their space and efficiency advantages over linear regulators. For the designer, however, the EMI and associated regulatory requirements can present a significant challenge. To specifically address EMI in switching regulators, a multi-phase, spread-spectrum silicon oscillator is an appropriate solution.
Once upon a time, if you wanted to know the future you went to a colorful character who told you your fortune by examining bird guts, tea leaves, or other obscure random pattern generator. They were called witch doctors, clairvoyants, and fortune-tellers. Today we call them business analysts.
The licensing arm for the HDMI standard governing the wired transfer of high-definition multimedia content between consumer electronics devices said an upgrade to the spec will be ready for industry-wide adoption by the end of next month.
Intended for use in harsh physical environments where long cable runs or EMI concerns preclude the use of copper-based interconnects, the V1121 conduction-cooled 10-Gigabit Ethernet (10GbE) XMC module from AdvancedIO Systems has dual front-panel optical interfaces.
Cherry's AN9 series dual output rotary position sensor is electrically and physically non contacting, making it appropriate for applications where high reliability and uncertain physical tolerances are involved. Its dual output design allows a connected controller to diagnose potential problems
Microsoft Corp. is rolling out a redesigned search site in the coming days and hopes it will lure more Web surfers than the two most recent incarnations, Live Search and MSN Search.
Containing a level shift high-side driver, low-side driver, bootstrap diodes, IGBTs, and free-wheel diodes, the M81500FP 500-V three-phase motor driverfrom Powerex occupies a footprint of 11.93 x 17.5 mm.
Provided in a 21 × 21 mm 449-pin BGA package, Renesas’ SH-NaviJ SH77722 is designed for use in compact portable navigation systems and low-end through mid-range dashboard-mounted car navigation and infotainment systems.
TDK Corporation has announced that it has developed soft termination MLCC capacitors that offer improved thermal and mechanical robustness. To address reliability issues with the C1005 (CC0402) through C3225 (CC1210) case sizes, TDK has developed a four-layer termination structure that exhibits
Google Inc. is hatching a new species of e-mail and instant messaging, but the Internet search leader first wants the hybrid service to evolve even more with the help of independent computer programmers.
