Tensilica has announced the immediate availability of the Digital Radio Mondiale (DRM) decoder on its popular HiFi 2 Audio DSP, which can be easily integrated into system-on-chip (SOC) designs. The implementation is based on software developed by Dolby and has passed Dolby's certification procedure. Now designers of digital radio systems can use one processor core -- Tensilica's HiFi 2 Audio DSP -- to run all decoders required throughout the worl...

Integrating all bias, control and power management functions into a single chip solution, the latest satellite low noise block (LNB) controllers from Zetex Semiconductors help to achieve LNB size reductions of up to 30%. Offered in 16-pin 3mm x 3mm and 4mm x 4mm QFN packages, the controllers require just 3 external components to function, 10 less than alternative single universal LNBs and 20 less than typical C-band LNB designs.

Requiring a single external resistor to very accurately set its output current, the ZXLD1350 from Zetex Semiconductors simplifies high power LED driving. Operating from an input supply of between 7V and 30V, the driver can produce an adjustable output current of up to 350mA, to support an LED chain of up to eight 1W LEDs.

Avago have today revealed the availability of a new family of optically-isolated voltage sensors. This family is the industry’s first series of optical isolation amplifiers based on sigma-delta modulation that is specifically optimized for voltage sensing.

Avago announced new precision optical isolation amplifiers for motor control and current sensing applications. The ACPL-790B, ACPL-790A and ACPL-7900 devices improve the accuracy and response times of the Avago isolation amplifier portfolio, while addressing compact applications with a smaller footprint package design. The high-precision isolation amplifiers are ideal for current and voltage sensing in AC and brushless DC motor drives, industrial...

Avago Technologies has introduced a series of high-speed optocouplers in Stretched Small Outline (SSO) packages with two new features: they are as much as 50 percent smaller than conventional dual-inline packages while providing up to 8 mm of creepage and clearance to meet stringent IEC, UL and CSA reinforced safety and insulation regulatory requirements. Applications for the SSO6 and SSO8 (6 and 8 pins, respectively) packages include digital log...

Avago Technologies has announced two new gate drive optocouplers in Stretched Small Outline (SSO) packages for AC and DC brushless motors used in home appliances and industrial applications. Avago's ACPL-W302 and ACPL-W314 gate drive optocouplers are an ideal solution for controlling variable-speed brushless motors in energy-efficient home appliances such as air conditioners and washing machines. Other applications include small- to medium-sized ...

Fully space-qualified power devices designed and made in Europe simplify procurement as space technology targets growing commercial opportunities

STMicroelectronics has announced a complete three-phase motor-control development kit based on the STM32 Flash microcontroller – launched mid-2007 – which provides all the necessary hardware and firmware to enable users to evaluate this 32-bit solution, and to begin development of their own sensorless motor-control application. The STM32 uses the powerful ARM Cortex-M3 core, developed specifically to address the requirements of cost-sensitiv...

STMicroelectronics, a leading provider of ICs for set-top boxes, has completed a demonstrator platform for next-generation STBs capable of receiving interactive digital television services via broadcast or broadband Internet connections.
