STMicroelectronics today unveiled its new RF synthesizer with integrated voltage-controlled oscillators (VCOs) with the highest frequency coverage in the market. ST’s STW81103 is the first single-chip device that operates up to 5GHz, meeting the increasing demand of equipment manufacturers for space and cost-efficient solutions in radio applications with frequencies in the microwave range. Among the applications in which these devices may find ...

Intersil has introduced the ISL3159E and ISL3179E RS-485/RS-422 transceivers. These next-generation interface ICs combine 40Mbps transmission performance over the industry’s widest temperature range (-40C to +125C) along with 15kV IEC61000 ESD protection and a DFN package option that is up to 70% smaller than standard 8-lead SOIC offerings.

CML Microcircuits today announced the introduction of a new RALCWI (Robust Advanced Low Complexity Waveform Interpolation) vocoder IC. The product is the result of a co-operation between CML Microcircuits and SPIRIT DSP. The new CML IC is named as the CMX618, which CML will market to worldwide communication markets based upon SPIRIT’s proprietary Low Bit-Rate Vocoder technology. The co-operation combines CML’s 39-year history of developing mi...

A huge potential market of untapped cell phone users in regions like India, China, Russia, South America and Africa want cell phone service, but can only afford very basic, entry-level, reduced-feature-set phones. With AnalogicTech’s AAT3193, designers building cell phones for these new markets can provide basic illumination for low-cost TFT-LCD panels in an extremely small footprint while requiring just two external components; a 1µF capacit...

PMC-Sierra has announced the availability of two fibre access gateway solutions - the MSP7150 EPON/GPON gateway SoC for Fibre To The Home (FTTH) and the MSP7140 VDSL2 gateway SoC for Fibre To The Node (FTTN). These SoCs deliver gigabit-per-second line-rate IPV4/V6 routing, Network Address Translation (NAT), Quality of Service (QoS), encryption and a multi-channel VoIP terminal adaptor, and consume less than 1.5W of power. PMC-Sierra’s fibre acc...

Avago Technologies has announced a new family of 10 GbE LRM transceivers incorporating electronic dispersion compensation (EDC). The new product family includes X2, XENPAK and XFP. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. Avago's new HFBR-707X2DEM X2 module reliably delivers 10G data rates in enterprise networking environments using multimode fibre.

Intersil has introduced the ISL1539, the latest addition to its family of line drivers featuring low power, very small footprint and extremely good linearity. The ISL1539 is the first monolithic, dual port, DSL line driver for 100 Mbps VDSL2 Central Office (CO) applications. The ISL1539 uses proprietary circuitry to achieve low distortion, high capacitance drive and less than 910mW/port total power consumption while delivering 20.5dBm output pow...

Texas Instruments has introduced a low-phase noise clock generator that provides best-in-class jitter performance at 380 femtoseconds (fs) (rms at 10 kHz to 20 MHz). The device incorporates crystal oscillator (XO) circuitry with a fully-integrated frequency synthesizer supporting a wide output frequency range from 10.9 MHz up to 766.7 MHz and from 875.2 MHz up to 1175 MHz, easing design for customers designing Ethernet, fibre channel, PCI Express...

Texas Instruments has today introduced the industry's smallest low-power, single-channel Gigabit Ethernet (GbE) serializer/deserializer (SerDes) device, enabling higher densities in data communications and telecommunications equipment. The new interface device combines a small 6-mm x 6-mm package with low power consumption at 200 mW to reduce board size and complexity and save power in Ethernet passive optical networks (EPON), GbE switches/router...

Analog Devices has introduced a two-chip IF (intermediate frequency) receiver solution that dramatically improves the data bandwidth and capacity of next-generation, multi-carrier wireless base stations compatible with emerging 3G cellular transmission standards. Analog Devices’ dual-channel AD8376 VGA (variable gain amplifier) and AD6655 IF diversity receiver solution replaces 48 discrete components, enabling 3G micro- and pico-cell base s...
