Optical on-board-transceiver carries up to 300 Gbit/s data FCI’s Leap On-Board-Transceiver (OBT) system is a one inch square, (2.5 x 2.5 cm) board mounted optical module that features 12-transmit and 12-receive channels, each working at 25 Gb/s over distances up to 100m with a total of 300 Gb/s throughput. The OBT is designed to be placed near a host ASIC which results in shorter copper board traces, better signal integrity and lower power consumption. The transceiver is connected to the board via an FCI proprietary surface mount electrical BGA/LGA socket. Optical connectivity to-and-from the OBT is realised by using a high-density ribbon fibre assembly connecting to the front panel with an optical connector system such as the MPO or MXC connector and adaptor. A standard MT ferrule is used on the transceiver side. This next generation of product has been engineered with the latest 850 nm VCSEL and PIN array technology operating at 25 Gb/s along with the latest 25 Gb/s laser driver and TIA chip set . The design is optimised for low power consumption resulting in a total typical power consumption of 2.7W without CDR and 5.4W with CDR. FCI www.fci.com DDR4 modules, SSDs for automotive and industrial markets At the upcoming Embedded World, Swissbit AG will showcase memories and storage solutions designed for automotive, industrial and data communications applications. Among the highlights are Solid-State Disks (SSDs) with ultra fast I/O as well as Swissbit’s first DDR4 DRAM module which offers significantly higher data rates without any negative effect on energy consumption. The latest generation of SSDs with SATA-III features an I/O bandwidth of 6 GBit/s. With its X60 series, Swissbit widens its SSD portfolio and increases the data throughput to 525 MByte/s with a random access I/O performance up to 75.000 IOPS. The series leverages Swissbit’s proprietary hardware and firmware functionality to address demanding embedded storage applications which require high performance, reliability and resilience over their entire service life. The X-60 products are available at capacities from 16 to 480 GByte and in standard form factors. Another innovation, Swissbit’s first DDR4 ECC SODIMM, the company serves the need to current embedded SBC boards. On top of higher I/O bandwidth, the module offer an optimised data bus termination, dynamic bus inversion and CRC protection of the instruction and data buses. With its DDR4 offerings, namely the 8GByte ECC SODIMM Swissbit targets industrial applications in the first place. With the extension of its PS-100u security series, Swissbit aims at highly integrated secure data storage applications. . Swissbit www.swissbit.com Sensor-integrated smart lighting manager enables IoT-connected daylight harvesting ams AG has introduced the AS721x Autonomous Daylighting Manager which the company claims is the industry’s first integrated chip-scale Internet of Things (IoT)-connected smart lighting manager. The new class of sensor-integrated smart lighting manager solutions delivers cost-effective, IoTconnected, integrated control capabilities to luminaire, light engine and replacement lamp manufacturers. Photopic sensors built with nano-optic filters integrated into the AS721x series are designed to help lighting manufacturers address the growing challenges of energy- saving lighting mandates, including daylighting controls. The challenges are more costeffectively met by bringing the controls, connectivity, such as Bluetooth, and high-granularity sensing into the luminaires themselves. The AS721x family is ams’ first platform technology of integrated sensor solutions that provide system-level sensing and control capabilities, reducing system costs and shortening time-to-market. The AS721x Autonomous Daylighting Manager senses the ambient daylight and enables the delivery of constant lux levels in the space by managing subtle adjustments as the amount of outside light varies. Integrating a sensor-based manager into each luminaire optimizes the overall responsiveness and efficiency of the lighting system. This also delivers accurate lumen maintenance over time and temperature variations. ams AG www.ams.com Active heat sink for LEDs integrates low-noise fan motor The service life of LEDs directly depends on their heat dissipation concept. Drastic temperature fluctuations will considerably shorten it, and overstepping the permitted chip temperature has a direct impact on the light yield. The use of extruded aluminium heat sinks for free convection already serves as an effective LED heat dissipation concept today. Fischer Elektronik is now specifically expanding its comprehensive product portfolio for weight-sensitive applications with an active LED heat dissipation concept under the article number LA LED 68. The base is made from a thermotechnically optimised aluminium hollow-chamber profile. Zhaga-conform LED modules can be directly bolted to the front of this by way of additional threads. There is also the option of fastening various LED modules from different manufacturers, as well as their holder systems, to the pre-threaded mounting plate with the help of an adapter screwed into the base section. A special low-noise fan motor in a round design is integrated in and fastened to the back of the base section. The motor has a double slide bearing and is designed for the special requirements of LED applications where noise and lifetimes are concerned. Custom mechanical processing, cover panels with ventilation slits, customised designs and surface coatings are also all available.
