Camera flash LED driver solutions delivers up to 1.2A, ultra-compact 1.3mm x 1.3mm package

SAN JOSE, USA: Micrel Inc. introduced the MIC2873/MIC2874, an ultra-compact, camera flash LED driver that integrates a 1.2A boost converter and LED driver circuit into a small 9 pin, 1.3mm by 1.3mm chip scale package.

Operating from 2.7V to 5.5V and featuring up to 92 percent efficiency, these solutions are ideally suited for Li-Ion battery operated portable applications such as phone cameras, tablet computers, handset video equipment, and digital cameras.  High switching frequencies (2MHz for the MIC2873 and 4MHz for the MIC2874) allow for the use of a miniature size chip inductor and small input/output capacitors, thereby reducing the total power footprint to a solution size to less than 10mm squared.

In addition, these devices can operate in either a flash or torch mode with the ability to provide a boost or linear output using a single wire communication interface or through external pins. The MIC2873/MIC2874 are available in volume with 1,000 quantities pricing starting at $0.26/$0.30 respectively.

Micrel's new generation of high brightness Flash LED drivers address the growing market of tablets and mobile phones by reducing solution size for LED flash applications with a 40 percent reduction in package size.

These parts are fully protected against overvoltage and overcurrent conditions with a configurable time-out feature.  In addition, these ICs provide LED short circuit detection and a true load disconnect feature for best system reliability.  The MIC2873/MIC2874 devices are fully specified with an ambient temperature range from -40 deg C to 85 deg C.

Fairview Microwave debuts comprehensive lines of IP67 RF adapters

ALLEN, USA: Fairview Microwave Inc., a pre-eminent supplier of on-demand microwave and RF components, introduces a comprehensive line of IP67 RF adapters commonly employed in the DAS, cellular, aviation and military industries due to their ingress protection from water and dust.

Fairview Microwave’s new RF adapters are IP67 rated, meaning they use advanced ingress protection to make them virtually impenetrable to contaminants like dust, sand, and water. Offered in this release are in-series adapters including 7/16 DIN, 4.1/9.5 mini-DIN, Type-N and TNC.

Between-series versions include 7/16 DIN to 4.1/9.5 mini-DIN, 7/16 DIN to Type-N and 4.1/9.5 mini-DIN to Type-N. They are compatible with all like-series connectors, cables and passive and active components. Each adapter operates to 6 GHz with excellent VSWR of 1.15:1 to 1:25:1 depending on the connector type.

Fairview’s ingress protected RF adapters also come in two different versions, “Mated” and “Unmated”. “Mated” adapters meet the requirements of IP67 only when both ends of the adapter are terminated in mating connectors.  “Unmated” adapters meet the requirements of IP67 even when one or both ends of the adapter are unterminated.

“In outdoor RF communications installations, ingress protection against dust and water is imperative. This new line of IP67 adapters offers the highest level of dust and water protection without the addition of costly and time-consuming weatherproofing tapes”, says Greg Arnold, Technical Sales Manager at Fairview Microwave. “Our extensive offering includes IP67 adapters compliant in the mated and unmated condition ensuring you get the level of protection you need.”

Grässlin bolsters product portfolio with talis motion and presence detectors

GERMANY: Both, increasing energy costs and a stronger ecological awareness make people consider their own energy consumption more thoroughly. And wouldn't you be grateful for a little support?

To this task Black Forest Grässlin GmbH has been committed for more than 50 years. With a large variety of time switch technology, lighting and also temperature control, the company is a global partner chosen for innovative energy solutions by now.

To make saving energy easier for their customers Grässlin now successively extends its offer by a broad range of presence and motion detectors.

The first launch comes with one outdoor motion detector and two indoor detectors.

Due to the amount of already established motion and presence detector brands Grässlin focused on a particularly simple handling, latest technology and a modern design to provide an added value compared to existing products.

A/D converters consume lowest power

BANGALORE, INDIA: Analog Devices Inc. (ADI) has introduced three ultra-low-power, multichannel, 12-bit, 1-MSPS SAR (successive approximation register) A/D converters.

The new 2, 4 and 8-channel A/D converters are designed for battery-powered data acquisition modules, handheld meters, field instruments and communications applications as well as medical devices such as portable electrocardiograms and heart rate monitors.

The A/D converters are the most power-efficient in their class, dissipating a maximum of 1.7 mW at 1 MSPS (mega-samples per second), which is over 60 percent less power than the closest SAR A/D converter competitor. The A/D converters are housed in a tiny 4-mm × 4-mm LFCSP package and feature a 5 ppm/°C typ on-chip internal reference.

NextG-Com announces first LTE protocol stack to target small cell relay nodes backhaul

STAINES, ENGLAND: NextG-Com, an expert in embedded software products and services for LTE, M2M and satellite communications, announced the availability of ALPS 521, a Release 11 compliant UE protocol stack designed for easy integration of relay node (RN) backhaul functionality with an existing eNodeB (eNB) solution. Relays are a key element of LTE-Advanced (LTE-A).

Traditionally, user equipment (UE) architectures are optimized for a high level of hardware integration, for example using an ASIC, and unlike eNB are based on different design approaches that focus on high volume and power efficiency. ALPS 521 is designed to provide interfaces to eNB network protocols via the NextG-Com IPC framework, and is pre-integrated with eNB RN interfaces to the scheduler and eNB controller entities.

"Our ALPS 521 LTE protocol variant offers a fast and effective way of delivering a small cell solution to infrastructure vendors who wish to extend their existing eNB portfolio to support future relay node features," said Denis Bidinost, NextG-Com CEO. "Our UE knowledge and expertise can help eNB vendors where additional development and integration services are required to bring the small cell relay node to market."

Using an in-house 3GPP test environment, ALPS 521 is pre-tested with RN-specific scenarios and configuration parameters, and can be flawlessly integrated into the relay architecture.

ALPS 521 is fully tested against relevant 3GPP/non 3GPP third party conformance tests specific for relays.

As it is already fully Release 11 compliant, ALPS 521 provides a simple platform for the integration and verification of the interactions of relay functionalities to Release 11 specifications such as impact of R-PDCCH and ePDCCH, CoMP, and relay interactions.

ALPS 521 is future-proof to support RN Layer 1 interfaces through an adaptation layer (L1A), which supports both in-band without isolation and out-band/in-band with isolation RF architecture. It is designed with well-proven L1 adaptation layer APIs that can be easily customized based on the different MAC and Physical Layer architecture. The protocol stack components are also supplied with a host of tools-Trace, ASN.1, SE-RTOSTM-to help deliver faster product development and reduce third party licensing costs.
