Iris gets you off the ground

A reference design for flyback topology ac/dc power supply circuits commonly found in dvd/cd players, set top boxes and an array of consumer devices is now available from International Rectifier. The IRISMPS4 uses IR’s IRIS4009 ac/dc integrated switcher as the main switch and control device. The design features a universal ac line input and a 12V 1A full load dc output. The IRIS4009 combines a control circuit and a low loss Hexfet power mosfet in a single five pin package for ac/dc power supplies up to 30W. It can handle over 60% more power than leading competing devices classified at the same power level, as a result of application specific silicon and package technologies. Compared to a discrete solution, the part reduces component count and board space by around 25%.

Samsung's fb dimm is not so dim

A 1Gbyte fully buffered, dual in line memory module (fb dimm) based on DDR2, designed to boost memory density and bandwidth to improve data processing in servers and workstations, is due to be sampling soon by Samsung. Explaining the emergence of fb dims, Samsung says that currently, the memory slot access rate per channel decreases as the memory bus speed increases, resulting in limited density build up as channel speeds increase. The fb dimm, however, eliminates this ‘stub-bus’ channel bottleneck by using point to point links that enable multiple memory modules to be connected serially to a given channel. A memory buffer chip is added to each module to enable the use of high and low speed interfaces. The buffer can generate speeds of 3.2 to 4.8Gbit/s, six times that of dram, according to Samsung.

Han DDD module with 40% increase in contact density

Capable of housing 17 Han-D connector inserts with crimp termination, the Han DDD module from Harting offers a 40% increase in contact density compared to earlier designs. The modules fit Han-Modular hinged frames and Harting’s Han-Modular Compact housing and suit signal transmission in industrial systems.

Zarlink adds circuit emulation services

Zarlink has added three low density circuit emulation services (ces) over packet processors to its circuit to packet device portfolio. The devices enable one to 32 TI/E1 streams of time division multiplex (tdm) traffic to be sent over any packet switched network. The ZL50120 family caters for one, two or four streams of tdm voice, video and data traffic, with associated timing and signalling, across Ethernet, IP and multiprotocol label switching networks. On chip sram capable of handling network delays of more than 100ms, means the ZL50120 family does not require external memory. Zarlink also claims chip count is minimised as the processors connect directly to a line interface unit or framer on the tdm side and to an Ethernet PHY on the packet side. A reference design, evaluation board and software application programming interface are available.

Toshiba's surface mount photocouplers

Designed for applications that need to combine high speed switching with isolation levels that meet international safety standards, are Toshiba’s latest surface mount photocouplers with 5kV isolation voltage. Supplied in a package that is just 6.8 x 4.5 x 3.6mm, the TLP70x and TLP71x 6pin sdip series are said to be 50% smaller than conventional 8pin DIP parts. Nevertheless, they offer the same functionality and isolation ratings – the use photo ics that are optically coupled to gallium arsenide IR emitting diode to provide minimum isolation levels of 5000V rms.

Fully differential amplifiers from Texas Instruments

Fully differential amplifiers from Texas Instruments have been designed to get the best performance from high speed a/d converters. The 1.9GHz THS4509, with what is said to be one third less settling time than previous fully differential amplifiers, has been designed with applications such as test and measurement, medical imaging and wireless infrastructure in mind. Made on TI’s bipolar SiGe process, the amplifier offers an input referred voltage noise of 2.0nV/rtHz, second and third order harmonic distortion at 70MHz of –80 and -87 dBc respectively.

Flash targets mainstream

Bringing flash into the mainstream is the target for Actel’s third generation of flash based programmable logic devices, the ProASIC3 and ProASIC3E families. Actel claims the parts are not only the lowest cost fpgas yet, but also deliver performance and security advantages over comparable sram based devices. They address consumer, automotive and other ‘cost conscious’ markets – the fastest growing segment of the fpga market at the moment, according to the company. The single chip devices deliver 64bit, 66MHz PCI performance, and have on chip user flash memory, useful for IP device addressing or user preference storage for example. Ranging in density from 30,000 to 1million system gates, they include secure in system programmability. The ProASIC3/E provides 1kbit of non volatile flash and clock conditioning circuits based on up to six onboard phase locked loops. The devices come with up to 504kbit of embedded dual port sram and up to 616 user I/Os, with 66MHz 64bit PCI performance. Densities for the ProASIC3/E family range from 600,000 to 3m system gates.

Sefram DAS 1200 ideal for troubleshooting or maintenance

Combining recorder, multimeter and oscilloscope functions in one unit, the Sefram DAS 1200 is said to be ideal for troubleshooting or maintenance applications. The unit has two fully isolated ‘universal’ inputs for dc or true rms (ac and dc) voltage and thermocouple signals. Eight additional low voltage digital inputs are designed for logic signals. The recorder features a sampling rate of 1MHz, 14bit resolution and comes with a 1Mbyte internal memory. In autoranging multimeter mode, the DAS 1200 can display two different measurements – for example, voltage and frequency – for each of the independently isolated input channels. The device weighs 1kg and can be battery powered for portability.

Focus on Phones

Texas Instruments has reached a significant technological waypoint by becoming one of the first semiconductor vendors to deliver a working product fabricated on a 65nm process. Delivering on its promise to shrink its 90nm design by 50% and to cut leakage power from idle transistors by a factor of 1000, TI has produced a wireless digital baseband processor. Showing intelligent integration, Infineon Technologies has combined a baseband processor with a quad band radio transceiver. The E-GOLDradio enables the baseband and RF functionality to be realised in less than 4cm2 of board space – about 30% less than the two chip solution. The part is also claimed to reduce the bill of materials by around 30% thanks to the integration of the capacitors and discrete components necessary in a two chip approach. The part is said to be particularly applicable to cost driven low to mid range phones, as it supports many features without the need for an application processor, such as a camera, MP3 playback, dual displays and polyphonic ringtones. As such it is expected to attract manufacturers of clam shell and ‘slider’ phones. For designs that do require an application processor, NEC has recently announced a part that integrates three ARM cores which targets terrestrial digital broadcast reception (see the relating feature on page 21). The MP211 also integrates NEC’s proprietary dsp core and all four cores are connected with a new bus architecture that allows them to share a single memory unit. “Parallel processing technology is key to enabling enhancement of future applications, especially those that require both high performance and low power consumption,” stated Yoshiharu Tamura, general manager, mobile terminal unit within NEC. “With the addition of the Linux operating system, we can expect greater usability and more efficient development.”
