Single system monitor saves space and increases accuracy, claims Maxim

Wed, Jun 09, 2021

Replacing five components, the MAX22530 is the latest addition to the MAXSafe Technology family by Maxim Integrated. The isolated, field side, self-powered 12-bit system monitor shrinks solution size by 40 per cent and tightens accuracy by a factor of 50, says the company, improving system uptime in automated distribution and sub-station applications.

The MAX22530 has four channels and integrates five components into a single IC. It is intended to be used by automation system designers to save board space, increase channel density and improve the accuracy of monitoring voltage and current inputs and enable operators to monitor the system with finer precision and reduced system downtimes.

The MAX22530 delivers a 50x improvement in monitoring measurement accuracy (from ±50 per cent to just ± one per cent) compared to the standard linear optocoupler isolation solutions made from discretes. It uses Maxim’s integrated isolation technology that combines a 12-bit ADC, a DC/DC converter, user-settable threshold detection levels and chip-level diagnostic capabilities. This combination enables 50x greater stability in current transfer ratio performance to achieve a stable sense resistor voltage, says Maxim.

The measurement accuracy across four voltage and current inputs means that the MAX22530 allows a 250mm² solution size, which is 40 per cent smaller that the 420mm² size for the closest competitive discrete solution

The MAX22530 joins the existing MAXSafe products which combine integrated and isolated micropower DC/DC converters and communications lines. These are used to power up field circuits that are isolated from the control-side power source while simplifying diagnostics in signal monitoring applications.

The MAX22530 is available from Maxim Integrated’s website now. There is also the MAX22530EVKIT# evaluation kit.

Maxim Integrated has a broad portfolio of semiconductors, tools and support, to deliver essential analogue solutions including efficient power, precision measurement, reliable connectivity and robust protection along with intelligent processing. Its customer base includes designers in application areas such as automotive, communications, consumer, data centre, healthcare, industrial and the IoT.

Xylon releases multi-channel HDR ISP IP suite for multiple video processing

Wed, Jun 09, 2021

For use with Xilinx programmable devices, ranging from the Artix-7 FPGAs to the latest Versal ACAP devices, the logicBricks high dynamic range (HDR) image signal processing (ISP) IP Suite enables parallel processing of multiple Ultra-HD video inputs. At the same time, it allows savings of up to 50 per cent of programmable logic in comparison to simple instantiation of multiple ISP pipelines, says Xylon.

The latest version of Xylon’s logicBricks IP suite enables crisp camera video under altering and rough lighting conditions in next-generation, multi-channel embedded systems for use in automotive, surveillance, medical and similar video and vision artificial intelligence (AI) applications.

The logicBricks HDR ISP IP suite is designed and optimised for Xilinx programmable devices.

“As the automotive industry progressively moves towards more automated driving implementations, the trend towards high resolution cameras and higher frame rates continues,” said Paul Zoratti, director of automotive solutions and system architect at Xilinx. The multi-camera ISP functionality will help automotive developers optimise cost, power, and performance in future advanced driver assistance systems (ADAS) and automated driving products, he added.

The suite’s key IP cores, the logiISP-UHD ISP pipeline and the logiHDR HDR pipeline, support parallel processing of multiple video inputs, resolutions up to 7680 x 7680 (including the popular 4K2Kp60 video resolution). It also supports the ability to merge two or three exposures, parallel pixel processing and different pixel formats. These IP cores are supplemented with automatic white balance (AWB) and automatic exposure (AE) software libraries that use video statistics data collected at the video inputs, software drivers, demo applications, reference SoC designs, and bit-accurate C models.

The HDR ISP IP suite enables application-specific tuning through modifications at different implementation stages, explained Roko Koncurat, Xylon’s ISP team lead. “The provided IP blocks can be arranged in many different ways to fully tune up the system for a specific application. While hardware engineers may configure and arrange IP blocks implemented in programmable logic in various ways, software engineers can further control the implemented ISP pipeline to adapt to changing use conditions,” he said.

The logicBricks HDR ISP IP suite can be demonstrated on different computer vision development platforms designed by Xylon. The logiREF-MULTICAM-ISP reference design is immediately available. It demonstrates parallel processing of four video camera inputs and works on the logiISP-ZU-GMSL2 evaluation kit. This kit is based on the Xilinx Zynq UltraScale+ MPSoC and includes four of Xylon’s 2.3 MP HDR logiCAM-GMSL2 automotive cameras configured to output raw Bayer video image. Xylon’s automotive cameras are Xilinx Artix-7 FPGA-based and users can re-install the HDR ISP functionality with the provided firmware and initialisation scripts.

In addition to the MPSoC-based demo kit, Xylon offers an Ultra HD reference design prepared for the logiVID-ACAP vision development kit based on the Xilinx Versal AI VCK190 evaluation kit. The reference design is developed with the Xilinx Vitis unified software platform and demonstrates parallel HDR ISP processing of three 7.4Mpixel automotive video cameras connected to the Xilinx Versal (ACAP) device.

CML dives in to semiconductor microwave RF ICs at IMS2021

Fri, Jun 04, 2021

At next week’s Live IEEE International Microwave Symposium (IMS), CML will introduce its SuRF (Semiconductor Microwave RF) family.

The family is CML’s range of high frequency, high bandwidth RFICs and MMICs for RF and mmWave applications. Devices have been designed to help accelerate the design of RF products operating in the mmWave and GHz frequencies.

Among the devices that visitors will see are the CMX90A003 (1W) and CMX90A004 (2W) 860 to 960MHz power amplifiers. These two-stage, fully matched MMIC power amplifiers deliver +29.5dBm (CMX90A003) or +32.5dBm (CMX90A004) of saturated power. Both devices use GaAs HBT technology. The CMX90A003 can be used as a booster power amplifier in sub-1GHz applications to extend the range of low power RF transceivers. The CMX90A004 is optimised to operate as a high-power final stage PA in wireless ISM applications.

There will also be the CMX90G301 (+1dB) and CMX90G302 (+2 dB) 1.4 to 7.1GHz positive gain slope amplifiers, designed to compensate for frequency related gain loss. They are based on GaAS pHEMT and combine low DC power, low noise and high gain in a cascadable MMIC.

CML will also be offering visitors the chance to learn more about the recently introduced CMX940 low-power Frac-N RF synthesiser. The CMX940 addresses the demand coming from OEMs for a high-performance, highly configurable RF synthesiser that can operate from 49 to 2040 MHz. It is claimed to deliver best-in-class phase noise and low levels of spurious products due to a high level of integration, which includes a wideband voltage controlled oscillator (VCO).

Due to Covid-19 restrictions there will be no live demonstrations during the in-person event in Atlanta, GA. A video demonstration of the CMX940 will be available, and SµRF evaluation boards will be on display.

Live IEEE International Microwave Symposium (IMS) takes place in Atlanta, Georgia, USA, between 7th and 10th June. CML will be exhibiting at booth 1341.
