Melexis announced the MLX71120 and MLX71121 integrated RF receiver series of automotive-qualified ICs with dual inputs. These are suited for low-cost antenna applications in unlicensed industrial-scientific-medical and short-range-device frequency bands in Europe and North America. The MLX71120 and MLX71121 feature an integrated FSK and ASK demodulator, 5 mm2 32-lead QFN package, and power range from 2.1V to 5.5V
Agilent Technologies Inc. added a 3GPP LTE modulation analysis option to its 89600 Series Vector Signal Analysis software to enable LTE signal analysis from baseband to antenna, on digitized or analog signals, both uplink and downlink. The 3GPP LTE option is designed to give R&D engineers
Texas Instruments Incorporated introduced an LED driver with an integrated 40V, 1.2A switch that can drive up to three 1W LEDs in series. The TPS61165 device’s features and input voltage range of 3V to 18V allow designers to manage multiple high-power LEDs used in single-cell, battery-powered applications or point-of-load designs with a 9V or 12V bus.
Tyco Electronics introduced its reference layout for ESD and over-current protection for HDM 1.3 interfaces. It uses proprietary 0.25 pF signal-to-ground-capacitance PESD protection devices and component placement and routing to help protect against ESD events. It also includes optional over-current protection on the +5V rail using the PolySwitch nanoSMD device. This ESD and reference layout
FCI introduced the Minitek CTW Active Latch, a low profile housing mateable with other elements in the modular system. The Minitek Active Latch is designed for use in harsh and high vibration environments and is appropriate for industrial or automotive applications. The 2 mm latch houses crimp-to-wire systems, enabling discrete wiring to be attached and unattached to PCB boards with an audible click.
Mitsubishi Electric completed development of the ML520G51 red laser diode with an optical output standard of 150 mW at 640 nm. It is intended for use in mobile projectors, laser show devices as well as in other applications in the industrial and medical environment. This red laser diode appears bright to the human eye and is capable of emitting deep reds in the 640 nm range.
STMicroelectronics introduced a quad high-side intelligent power switch (IPS) -- the VNI4140K -- which is produced using the latest generation of ST’s VIPower technology to achieve a 50 percent saving in Rds(on) compared to earlier devices with the same die size, officials said. The reduction in on-resistance and quiescent current saves energy through lower losses. IPS devices integrate a logic interface, drivers and protection circuits on the same chip as a power stage
Strategic Test announced the UF2e-6110 two-channel 125 MS/s 8-bit Arbitrary Waveform Generator (AWG) PCI Express card. With synchronous multi-channel capability, the AWG card is suited for creating complex waveforms in applications that include I&Q signal generation, RADAR system development, communications testing, laser positioning, and HDTV signal generation
Texas Instruments introduced a single-chip, interleaved power factor correction (PFC) control circuit for multi-kilowatt communications, server and industrial systems. In line-operated systems with power levels from 75W to 1 kW and above, the UCC28070 helps reduce total harmonic distortion, allowing systems to maximize usable outlet power and accommodate extreme variations and disturbances
UNIPOWER announced a series of hot-swap, high power density telecom inverters. The INV1000 Series are 1000VA/800W and 1500VA/1200W sine wave inverter modules which operate from a 48V DC input and provide either a 115V AC or 230V AC nominal output.
Because of its inherent benefits including decreases to development times and increases in component compatibility, COTS (commercial-off-the-shelf) has been adopted by a vast number of industries, including the aerospace, military and space exploration markets. Most embedded systems within aerospace and military applications perform a function in some way related to mission-critical operation of the larger system and/or platform, making performance, reliability and functionality imperative to the design and manufacture of the embedded computing system. These systems must therefore operate flawlessly in very specific and defined ways while exposed to extreme environments, including high shock and vibration resistance, wide, dynamic temperature ranges, high humidity (or immersion), and the absolute vacuum of deep space.
In today’s world, wireless networks are becoming more ubiquitous, and they are implemented using a variety of protocols that are specifically designed for radio frequency systems. Some protocols that are in use are proprietary to individual vendors, while others are industry standards. Recently, a lot of attention has been given to 802.15.4 and ZigBee, but there is still some ambiguity as to what is different about 802.15.4 and ZigBee and what kind of networks or systems would benefit from these particular protocols.
If you got a head start on your holiday shopping in the days before Thanksgiving, you were greeted at Amazon.com with a message by founder and CEO Jeff Bezos announcing the release of Kindle, the company’s handheld e-book reading device. I have to admit, when a colleague first told me about Kindle, I reacted with a great big yawn.
Allegro MicroSystems introduced two automotive grade (temperature and voltage rated) three phase BLDC motor controller integrated circuits. These control ICs integrate the commutation logic on-board, which lessons the burden on the system microprocessor. If desired, the Hall sensor inputs can be driven directly by a microprocessor, which makes
