Reader O f f er Win one of five SoCKIT evaluation kits The SoCKIT evaluation kit is Arrow’s latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric. Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics gives away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe. The SoCKIT evaluation kit is fitted with a High Speed Mezzanine Connector (HSMC) including transceivers, two banks of low-power DDR3 memory, a MicroSD card and Ethernet 10/100/1000 interfaces, as well as an adjustable clock output by Silicon Labs. A 128x64 graphic LCD, VGA and audio connections, USB 2.0 OTG (Full Speed) and USB to UART connections, a 3-axis digital accelerometer and a temperature sensor complete the board. The kit comes with a user’s manual and USB and power cables. Check the reader offer online at www.electronics-eetimes.com Ultra compact DC-DC converters offer a voltage trim capability Murata has added to the company’s LXDC series of ultra compact DC-DC Converters with new devices that comprise the LXDC55F and LXDC55K step down converters. Both models offer a voltage trim function that allows adjustment of the output voltage within the range of 0.8 to 5.3 VDC for the 55F and up to 3.6 VDC for the 55K converter. The LXDC55FAAA-203 measures 5.0x5.7x2.1mm and can support an input voltage in the range of 4.0 to 14.0 VDC. Maximum output current is up to 1.5 A. Capable of supporting an output current up to 3 A the LXDC55KAAA 205 operates with an input voltage within the 2.7 to 5.5 VDC range. The Converters are constructed on a Multilayer ferrite substrate that integrates an embedded Inductor and the power IC. Using this approach the LXDC family exhibits good EMI suppression and reduced harmonic noise characteristics. The Converters use a synchronous rectifier technology. They are ideal for applications that require an extremely small DC-DC conversion footprint where a discrete approach is not possible due to space limitations. The LXDC series are aimed not only at consumer electronic devices such as cellular phones, tablets, games consoles, digital cameras but also at communication applications such as base stations. Murata Europe www.murata.eu Industrial USB camera delivers 2592x1944 pixels at 15fps in a 23x26.5x21.5mm casing With the XS, IDS is launching a generation of cameras that combines the convenient operation of a standard consumer camera, along with the versatility of a robust industrial camera. The 23x26.5x21.5mm unit weighs just 12 grams and can be integrated very easily into any system. Its magnesium housing makes it very robust. The camera is connected using USB 2.0 and a mini-B socket, and the Power Supply is provided by the bus cable. The 5 megapixel Aptina CMOS sensor with a pixel size of 1.4 μm delivers exceptionally detailed true color images, with a choice of seven fixed image formats: 5 MP, 3 MP, Full HD, UXGA (1600x1200), 1.2 MP, 720p, VGA. The frame rate is freely adjustable (e.g. for long exposures), and at full resolution of 2592x1944 pixels 15 frames per second can be captured in JPEG mode. Binning can be used to achieve frame rates as high as 30 fps. The integrated auto focus optical system delivers a crisp image from distances of just 10 cm, either automatically or manually using software. The associated API function also enables the current focus position to be read. A digital zoom allows easy and almost continuous enlargement of smaller sections of the image. The XS comes complete with the comprehensive IDS Software suite, including drivers, tools and interfaces. IDS Imaging Development Systems www.ids-imaging.com Industry’s first ultra-wideband Doherty amplifiers support broadband operation NXP Semiconductors N.V. has introduced an ultra-wideband Doherty reference design using the BLF884P and BLF884PS – the industry’s first wideband Doherty power Amplifiers capable of broadband operation (470 to 806 MHz). The new 70 W DVB-T LDMOS designs bring the high-efficiency gains of Doherty topologies to broadcast transmitters, using NXP’s patent-pending architecture capable of operating across an ultra-wideband spectrum. Whereas traditional UHF technologies such as class AB typically reach only 30% efficiency, Doherty solutions are capable of reaching 45-50% power amplifier efficiency. The ultra-wideband Doherty design uses NXP’s mature leading-edge 50 V LDMOS technology, and the ruggedness of the BLF884P and BLF884PS make them ideal for digital broadcast transmitters. Mark Murphy, director of marketing, RF power and base stations, NXP Semiconductors, said: “Given the immense pressure to deliver richer content via high-performance TV transmitters, we believe that the impact of ultra-wideband Doherty architectures on the overall digital broadcast market will be wide-ranging. At an average DVB-T power level of 70 W, the BLF884P/PS ultra-wideband Doherty reference design is extremely well suited for gap filler applications.” NXP Semiconductors N.V. www.nxp.com 46 Electronic Engineering Times Europe June 2013 www.electronics-eetimes.com
