Analog Devices Digital-to-Analog Converters
The 12-bit AD5767 and 16-bit AD5766 are devices with all the required bias ranges for coherent optical systems of medium to long-haul, fiber-based telecommunication deployments. Both ICs integrate an array of discrete components to provide the required voltage ranges and additional system functionality in a very small area. These D/A converters are well-suited for optical modules and electro-optical functions such as bias control, including Mach-Zehnder modulator-bias control.
The converters are available in both 4×4 mm WLCSP and a 6×6 mm LFCSP packages. They provide a range of unipolar or bipolar output voltages from the user-supplied 2.5-V reference; these outputs can be adjusted down to −20 V or as high as +14 V.
Detailed technical schematics are available on Analog Devices’ website.
BQR Maintenance Tool
BQR-Digital aims to enable analysis for virtually all the components in the facility, yielding a comprehensive overview. By contrast, IOT-based systems are typically connected to only a small number of components.
The tool enables predictive maintenance; when a component status is diagnosed as critical, it can be replaced or monitored, and preparations can be made, preventing high damages when the component actually fails. BQR-Digital can also be connected to any CMMS via the web, immediately providing actionable information.

Microsemi Upgrades its Imaging/Video System
"Our CSI-2 FMC daughter board bundled with our IP enables customers to quickly design a wide variety of imaging solutions. In addition, the low power of our IGLOO2 and SmartFusion2 FPGAs are particularly compelling for camera designs which are often size and power constrained," said Ted Marena, director FPGA marketing at Microsemi. The MIPI CSI-2 receiver decoder IP supports multi-lane (one, two and four lanes), RAW8 (eight bit data width), and both short packet and long packet formats for transporting image data.

Synopsys Embedded Vision Processor
The CNN engine delivers up to 4.5 TeraMACs per second when implemented in 16-nanometer FinFET process technologies under typical conditions, four times more performance than Synopsys' previous CNN engine. It also supports both coefficient and feature map compression/decompression to reduce data bandwidth requirements and decrease power consumption.
The vision CPU scales from one to four vector DSPs and operates in parallel to the CNN engine, delivering maximum throughput for a broad range of high-performance embedded vision applications such as advanced driver assistance systems (ADAS), video surveillance, augmented and virtual reality, and simultaneous localization and mapping (SLAM).
The enhancements are scheduled to rollout in August and October of this year. For more details, visit Synopsys’ website.
TI Frequency Inverter Reference Design
The Three-Phase High-Frequency GaN Inverter Reference Design features TI's LMG3410 600-V, 12-A GaN power module with an integrated FET, gate driver and protection, announced last year. The GaN module allows the design to switch up to 5x faster than silicon FETs, while achieving efficiency levels greater than 98 percent at 100 kHz and greater than 99 percent at 24 kHz pulse width modulation (PWM) frequency.
With GaN, designers can optimize switch performance to reduce power loss in the motor, and downsize the heat sink to save board space. Operating the inverter at 100 kHz significantly helps improve torque ripple when used with low-inductance motors.
