At your digital radios! In this month’s reader offer, CML Microcircuits is giving away two complete evaluation kits for its newly launched CMX983 Reader O f f er analogue front end, a chip that bridges the gap between a digital radio’s RF section and the DSP/FPGA. Specifically designed to meet the needs of a Software Defined Radio (SDR), the CMX983 performs critical DSP-intensive functions, provides dual-channel analogue-to-digital and digitalto analogue conversion. It includes two RF fractional-N synthesisers and embeds a host of auxiliary ADCs and DACs for use within the radio system. Included in each package are five highly configurable CMX983 ICs, supporting numerous sample rates and filtering characteristics. A software support package is also included in this offer. For evaluation of the Fractional-N synthesisers, the EV9830 evaluation kit includes a 900MHz VCO fitted with connections to synthesiser 1 and a 2.1GHz VCO fitted with connections to synthesiser 2. Test pads are also provided for connection to an external VCO. An instrumentation interface with single-ended signal connections to differential baseband I/Q connections on the CMX983 is provided to allow easy connection of proprietary test equipment. The board also incorporates all of the necessary power supply regulation facilities for operation from a dual +/‑6Vsupply. CML Microcircuits www.cmlmicro.com Check the reader offer online at www.electronics-eetimes.com LED-driver ICs deliver accurate output power to 12 W Power Integrations has introduced a IC family of isolated LED drivers which delivers up to 12 W of accurately controlled output power, reduces component count and results in simpler, smaller, more reliable LED lighting designs. LYTSwitch-2 LED-driver ICs use primary-side control, resulting in cost-effective, single-sided PCBs with low component counts. In addition, driver isolation allows the LEDs to be affixed directly to a metal heat sink, avoiding the added expense of an electrically isolating enclosure that is often required for non-isolated drivers. Accurate constant-current (CC) output tolerance across temperature (better than +/-5% at both low-line and high-line voltages) reduces the need to over-design systems in order to meet requirements such as the U.S. ENERGY STAR minimum-lumens-delivered specification. Designs using LYTSwitch-2 ICs are also highly efficient – up to 90% in typical applications. LYTSwitch-2 ICs protect the LED load from surges in line voltage, increasing bulb lifetime in regions where the mains voltage is subject to frequent peaks. The constant-current and constant-voltage (CC/CV) control function maintains a constant voltage on the output of the driver during no-load operation, preventing damage to the output filter or shutting down the driver when being tested or installed with no LED string connected. Power Integrations www.powerint.com Digital-lighting microcontroller uses discrete state-machine controllers The STLUX development environment, consisting of demonstration boards, a graphical configurator, software libraries, and compiler, provides everything needed to start designing high-performance LED lighting with STLUX385A, the first in a new family of lighting controllers featuring a new digital control technique from STMicroelectronics. The STLUX development environment is demonstrated with a plugand play demonstration board featuring all STLUX385A functionalities and a context for programming PWM waveforms using the six on-chip SMED (State Machines Event Driven) digital controllers. The SMED is an advanced hardware-configurable state machine where state advancement is automatically triggered by internal or external events thereby ensuring faster response than a conventional interrupt-driven microprocessor. STLUX385A supports smart-grid connectivity and DALI communication for remote control, enabling use in energy-efficient lighting throughout smart cities. The STLUX385A includes six SMEDs with 10ns reaction time, four analogue comparators with internally-generated and external references, an analogue-todigital Converter (ADC) with an 8-channel sequencer, native DALI, built-in memory including 32 kBytes program Flash, serial and I²C communication channels, and an integrated low-power STM8 microcontroller. STLUX www.stlux.org More HDD memory for a 24/7 surveillance society The MD03ACA-V series of high-capacity hard disk drive (HDD) unveiled by Toshiba Electronics Europe is a purpose-built line of 3.5-inch HDDs addressing the video surveillance market with capacities up to 4TB. The SATA drives spin at 7200rpm and support the industry-standard 512n sector lengths as well as RV compensation that maintains performance under multiple HDD configuration - making the MD03ACA-V series well suited for around-the-clock 24/7 video surveillance storage. The robust design of the MD03ACA-V series provides storage to various video recorders including surveillance digital video recorders (SDVR), surveillance network video recorders (SNVR) and Hybrid SDVR, delivering 24/7 operation with a mean time to failure (MTTF) of 1 million hours. The higher memory capacity supports higher resolution data streams, addresses the need for longer surveillance video retention periods, multi-streaming capabilities, wider temperature resistance and uninterrupted write applications.
