In October of 1981, three semiconductor companies announced the open-architecture VMEbus, spawned by the introduction of the Motorola 68000 microprocessor. After 27 years, the VMEbus still holds the largest market share of all buses and boards. Today's bus technologies have lives measured in months, so why has the VMEbus survived and prospered while other buses have rapidly gone by the wayside? (Engineers use the terms VMEbus and VME interchangeably.)
Operating from 700 MHz to 1,000 MHz, Maxim Integrated Products’ MAX19985A dual downconversion mixer provides 2 independent downconversion channels, each with a typical IIP3 of 25.5 dBm, typical conversion gain of 8.7 dB, and typical noise figure of 9 dB. The 6-mm x 6-mm 36-pin TQFN-packaged component offers a 2LO-2RF spurious rejection of 76 dBc for an RF level of -10 dBm and 71 dBc for a level of -5 dBm. The SiGe downconverter
Addressing power-conscious systems such as those in portable devices, the TSH122 video buffer IC from STMicroelectronics has an operating current of 1.7 mA and what is presented as the lowest standby current among comparable devices, 4 nA typical, 500 nA maximum. The input voltage range is from 2.2 to 5 V, and features include a differential gain of 0.5%, a differential phase of 0.5 degrees, and a group delay of 10 ns. Attenuation at 27 MHz is typically
All around, 2008 has been a very trying year. Each day seemed to bring a new round of bad news, whether it was the real estate bubble bursting, stock markets plummeting, or the “big three” automakers petitioning congress for a bailout similar to the one given to some of the nation’s largest banks. In the electronics industry, lackluster consumer confidence, fueled by the global economic crisis...
Incorporating an IR SSLD and an I²C/SMBus interface, Intersil’s ISL29015 ambient and infrared light-to-digital converter executes ambient light and infrared sensing. The 2-mm × 2.100-mm 6-lead ODFN-packaged component uses an internal 16-bit ADC with adjustable conversion time from 25 ìs to 100 ms and flicker noise rejection of 50 Hz and 60 Hz. For
Possessing character heights of 0.28” (7 mm), 0.39” (10 mm) and 0.56” (14.22 mm), Avago Technologies’ HDSM-28xx, HDSM-29xx, HDSM-43xx, HDSM-44xx, HDSM-53xx, and HDSM-54xx single- and dual-digit 7-segment displays perform in home appliances, exercise equipment, TV set-top boxes, measurement equipment, and warning indicators. The SMT devices are built on a PCB substrate with metal tabs or end caps that can
Compatible with the NI Sound and Vibration Measurement Suite, a collection of analysis and signal processing tools, a wireless data acquisition module and two PXI Express modules from National Instruments offer improved performance over previous devices of this type.
Supporting both synchronous and non-synchronous designs, a single output, step-down controller from Advanced Analogic Technologies is capable of providing power conversion for lower-cost 12-V adapters. Offering both high and low-side pins, the controller supports a 6-V to 24-V input range
Based on the 45-nm Intel Core 2 Quad processor, the Kontron KTG41/ATX ATX basic motherboard and the Kontron KTG41/ATXU Micro-ATX basic motherboard offer 3 years long-term availability. The processor's specs include a 3.0 GHz, 12-MB L2 cache and an FSB of up to 1,333 MHz
Made for the Heavycon Series plug connectors, Phoenix Contact’s Series B push-in contact inserts can connect flexible wires with ferrules or rigid wires without tools. To key the contact, the user inserts plastic pins into the contact coding slot without removing the fastening screws. The product come in 6, 10, 16, and 24 positions for 500-V/16-A with
Supplying up to 365 W, Digital Power’s HD365 Series AC/DC switching power supplies present a power density of 18 W/in.³. The 3” × 5” devices offer output voltages of 5 V, 12 V, 24 V, and 48 V; universal AC input from 85 V to 264 V, standby voltage of 5 V, and isolated 12-V auxiliary outputs. The open-frame switchers exhibit active power factor
For members of the electronics supply chain, going “green” is not just a short-term marketing scheme rife with buzzwords but short on substance. Granted, the tech sector has jumped on its share of bandwagons, but this movement is different. It’s not just about pioneering technologies, building a positive public image, padding the bottom line or even “doing the right thing.” It’s all of the above. When state-of-the-art electronic products are energy efficient, environmentally sustainable, and cost effective, everyone wins.
Included in the WEBENCH Sensor Designer Tool, National Semiconductor’s LMP2021 (single) and LMP2022 (dual) zero-drift operational amplifiers present an input voltage noise of 11 nV/sqrt Hz at a gain of 1,000 V/V. The components use EMI suppression filters, demonstrate an EMI rejection ratio (EMIRR) of 79 dB, support 24-bit data acquisition systems, and optimally drive the ADC161S626 16-bit ADCs. The products offer input offset
