PRODUCTS EDITOR’S CHOICE DUAL 420WATT POWERFLEX DC POWER SUPPLY
360Watts of total power with each output variable between 60V at 3A and 16V at 10A. When placed in V- Track mode the outputs can be wired in series or parallel to provide up to 120Volts or 20Amps. New features include an S-Lock

im-TTi has launched a new mid power dual output
laboratory power supply based upon its PowerFlex regulation technology, replacing the original CPX200. The new models are capable of providing up to
design, which digitally locks the analogue control settings at the touch of a button, and range control which allows the rotary controls to be set to cover any voltage or current range chosen. Synchronous on/off ensures that
both outputs are switched at exactly the same time from a single button. The instrument includes full bus control via USB, RS232, GPIB and
LXI compliant LAN interfaces. It also has duplicate power and sense terminals at the rear. Both models are housed in a
compact half-rack wide, 3U high casing. The series is designed to meet the need for flexibility in the choice of voltage and current. The design of the CPX series enables higher currents to be generated at lower voltages within an overall power limit envelope. Each output can provide
considerably higher current than a conventional PSU of the same maximum voltage and power.

3D SOUND SOFTWARE ENHANCEMENT
Cadence Design Systems, Inc. and Sonic Emotion, a specialist in 3D sound entertainment, have announced that an optimised port of Sonic Emotion’s Absolute 3D sound software is now available on the Cadence Tensilica HiFi Audio/Voice digital signal processing (DSP) family. The company’s advise, this is the first time this sound software has been ported to a licensable IP DSP core. “By providing an optimised port of our software on the HiFi DSP cores, we can bring our Absolute 3D
sound technology to a broad range of OEMs and end-equipment manufacturers producing mobile and home audio devices, including TVs. This helps these device makers differentiate their products by providing a more compelling user experience,” said Rajeev Kapur, CEO of Sonic Emotion. This 3D post-processing technology is claimed to provide premium audio quality, enabling the creation of
a natural virtual 3D sound field across an entire listening area. This brings a hyper-realistic and immersive audio experience no matter where the device or listeners are positioned in order to enjoy their favourite movies, music and games, ensuring premium sound. “We’re seeing strong demand from our HiFi licensees to provide innovative audio/voice differentiated
software solutions to allow their products to stand out, and we are getting strong interest for this efficient 3D sound experience,” stated Larry Przywara, Director of audio/voice IP marketing at Cadence. The Tensilica HiFi Mini Audio/Voice DSP IP core is claimed to be optimised for the lowest power consumption,
enabling always-on listening. As part of the HiFi family of DSP cores, the IP core features more than 125 software packages that have been ported to the HiFi architecture by Cadence and more than 55 partners. Cadence Design Systems

line and new to RS stock is the Delphi Weather Pack connector series. These connections are environmentally sealed and are designed to withstand exposure to harsh conditions. They feature tin-plated terminals with special core wings, which enable crimp-only connections and thus remove the necessity for soldering.

Ideal Power has launched a new tool that calculates the average efficiency that an external power supply must conform with to meet ErPII II, stage 2. This new tool is extremely quick and at a glance helps work out what average efficiency value the power supply of their application or product is required to meet. By simply inputting an output voltage and wattage, the calculator will use the official formula set by the 278/2009 ErPII II compliance in the 2005/32/EC Directive, to provide the average efficiency rate required.

RF DIGITAL STEP ATTENUATOR ACCURACY & CONTROL
Peregrine Semiconductor Corp. has introduced its next-generation, UltraCMOS PE4312 DSA. These latest devices enable wide dynamic-range network-infrastructure designs that require highly accurate and efficient amplitude control. This DSA upgrade is ideally suited for
wireless-infrastructure devices, broadband consumer and infrastructure equipment, land mobile radios (LMRs), test-and-measurement equipment and military RF applications. This DSA meets a low insertion loss of 2.1dB
at 4GHz at any power-supply level between 2.3V and 5.5V. It also handles a wide temperature range between -40 and 1050 1.8V and 3V control logic.
C and supports both In addition, the PE4312 is claimed to offer
several improvements over PE4302 in attenuation accuracy ±(0.15 + 2 percent of attenuation setting), linearity (IIP3 of 59 dBm) and switching speed (500 ns). Finally, they features a novel architecture to provide safe attenuation-state-transition behaviour, which prevents positive power spikes that occur during attenuation-state changes when RF input power is applied. This feature simplifies the digital- interface design, improves signal quality and prevents damage to power amplifier sub- assemblies. Peregrine Semiconductor Corp.
