The Spartan-3A DSP low power (LP) devices are said to deliver a 50 percent static power savings, and a 70 percent savings while in suspend mode, compared to the standard devices, and they are available in industrial rated grades.
Endicott Interconnect Technologies’ HyperBGA PTFE-based coreless semiconductor package enables silicon devices to run at high speeds. The combination of the low loss, low dielectric constant material and strip line cross sections enables signal speeds surpassing 12 Gb/s. The material compliance of the PTFE, combined with the dimensional stability of a copper-invar-copper center plane
Phoenix Contact releases its QC (Quick Connect) 1.5 plugs, an insulation displacement connection (IDC)-based plug for use in an expanded range of wire gauges. They offer flexibility in wire selections (24 AWG to 16 AWG), they are designed on a 5 mm pitch (centerline) spacing and they come with or without mounting flanges. The plugs mate with proprietary 5 mm headers, enabling vertical, horizontal or lengthwise PCB mounting for wider range flexibility.
Kinetic Systems introduces high-performance breadboards that provide a flat, stable surface for a variety of applications that include mounting or assembling lasers, small optical systems, prototyping and precise inspections. Available in four standard configurations, these breadboards feature high natural frequency, nominal broadband damping, and flatness of ±0.004" over a 24" × 24" area.
Elmo Motion Control introduced three miniature servo drives that support up to 2,400W. The new Whistle servo drives achieve high power density coupled with SimplIQ intelligence and are available in the following additional models: WHI-15/60 (15A, 60VDC), WHI-10/100 (10A, 100V), WHI-15/100 (15A, 100V). By integrating the company’s FASST (Fast And Soft Switching Technology) power management technology with thermal management technology, the miniature Whistle exhibits a power density of 35 W/cm3.
Laird Technologies announces that 31 fingerstock standard products made from Recyclable Clean Copper (RCC) that offer similar performance characteristics to beryllium copper (BeCu) products, and they will work in 80 percent of all applications where BeCu is now used. RCC products do not contain beryllium, giving customers who want to avoid the use of beryllium containing metals a choice in alloy selections
Haydon Switch & Instrument, Inc. announces its size 11 hybrid linear actuators with an integrated connector. Offered alone or with a harness assembly, this connector is RoHS compliant and features a positive latch in order for high connection integrity. The connector is rated up to 3A and the mating connector will handle a range of wire gauges from 22 to 28.
Many different standards for wireless communications equipment are in use today. Narrowband communication standards use stronger transmission in a small slice of bandwidth. Wideband standards use lower transmission power across a larger bandwidth. Each standard defines minimum performance characteristics for receivers, and includes specifications such as bandwidth, maximum signal level, and sensitivity. GSM is one narrowband example; the channel bandwidth is 200 kHz. A GSM receiver must have a minimum sensitivity of –104 dBm and be able to tolerate a –13 dBm signal at the antenna. In contrast, CDMA2000 is a wideband standard that uses a 1.25 MHz bandwidth. CDMA2000 receivers need to have a minimum sensitivity of –117 dBm/1.25 MHz and tolerate a maximum signal of –30 dBm at 900 kHz offset.1
"Cost still rules applications," said Ross Bannatyne, Marketing Director at Silicon Laboratories, a supplier of 8051-based MCUs. "If 8-bit MCUs solve problems, why use more expensive 32-bit chips?" Newer 8051 derivatives, for example, execute 100 MIPS and on-chip multiply-accumulate accelerators let them handle signal-processing tasks. According to Bannatyne, some engineers might not realize 32-bit MCUs can incur code penalties. "They might assume an algorithm that requires 16 KB in an 8-bit MCU also needs 16 KB in a 32-bit processor. Often the code takes more memory in the 32-bit processor, often much more."
Texas Instruments Incorporated introduced what is said to be the industry’s lowest power zero-crossover operational amplifier (op amp). Featuring a unique single-input-stage architecture, the OPA369 achieves rail-to-rail performance without input crossover to solve the common design problem of input offset distortion due to the change in common mode voltage that is very prominent in low-voltage, rail-to-rail applications. Combined with 1µA quiescent current, SC70 package and operation down to
Anderson Power Products offers its multi-axial rotational connector (MARC). Suitable for medical and mobility applications, the MARC is designed to mate while traveling through an arc with a 3" minimum radius. It is rated to 30 while combining power, signal and ground circuitry into one package. Featuring eight Powerpole circuits integrated into a blind mate housing, the two-row horizontally oriented connector uses proprietary flat wiping contacts.
FCI extended its Gig-Array high-speed, high-density product line with 25 mm plug connectors. These mezzanine connectors provide either 200 or 296 signal contacts, and they add the capability for 40 mm stack height when used with the company’s existing 15 mm receptacles. The 25 mm plug connectors can also be paired with 5 mm receptacle connectors to provide an additional option to achieve 30 mm board-to-board spacing.
