FPGA cores support any media over any network Xilinx’ latest generation of Video over IP connectivity solutions address the industry’s transition to all IP-based networks. These connectivity solutions enable ‘any media over any network’ transport capabilities to the broadcast and pro a/v markets. Xilinx defines and deploys Video over IP protocols for contribution and distribution networks with the provision of the SMPTE ST 2022-1,2 and SMPTE ST 2022-5.6 IP cores and reference designs. These cores encapsulate multiple compressed JPEG 2000 or MPEG transport streams (MPEG-TS), or uncompressed SDI streams onto 1Gb and 10Gb Ethernet IP networks, and offer optional forward error correction (FEC) to recover lost packets and provide robustness in media transmission. The new Video over IP cores and reference designs support the SMPTE ST 2022-7 seamless (hitless) protection switching standard and are available with Xilinx Kintex-7 FPGAs and Zynq-7000 All Programmable SoCs, using FPGA Mezzanine Cards (FMCs) from Xilinx Alliance Members, inrevium AMERICA and Faster Technology. Additional SMPTE ST 2022-compliant IP cores include a brand new high-channel count Video over IP Forward Error Correction (FEC) engine that handles up to 512 transport streams. To address timing and synchronization techniques based on the IEEE1588 Precision Time Protocol (PTP) over local and wide area networks, Xilinx has developed IP cores and reference designs that enable the distribution of video sync signals over IP networks, and generate clocks and timestamps for remote video sources. Xilinx www.xilinx.com Isolated gate driver operates at up to 225°C CISSOID’s 2nd generation of HADES highly integrated isolated gate drivers is aimed at high density power converters, motor drives and actuators based either on fast switching Silicon Carbide (SiC) transistors, traditional power MOSFETs and IGBTs. The gate driver HADES v2 brings high reliability and extended life time in harsh environments, available in hermetic packages for extreme temperature applications up to 225°C, as well as in plastic packages for systems where extended life time is the priority and temperature doesn’t exceed 175°C. The HADES v2 gate driver includes all the functions to drive the gates of power switches in an isolated, high voltage half bridge. The chipset uses three integrated circuits: HADES2P on the primary side, HADES2S on the secondary, and the recently introduced quad-diode ELARA. Both primary and secondary chips come in ceramic QFP 32 pins or in plastic QFP 44 pins. The primary side IC (HADES2P) embeds a current-mode fly-back controller with an integrated 0.8Ohm - 80V switch, configurable non-overlapping and Under- Voltage Lockout (UVLO) fault management. It also includes a four channels isolated signal transceiver (2 Tx and 2 Rx) for PWM and fault signals transmission towards or back from secondary side through tiny pulse transformers. The two secondary side ICs (HADES2S), one for the high side and one for the low side, include a 12A driver, UVLO, Desaturation and Over Temperature Protection (OTP) fault detection circuits, as well as a two channels isolated signal transceiver. An Evaluation Kit (EVK-HADES2) is also available, which demonstrates a half-bridge built on the HADES v2 gate driver and two CISSOID’s NEPTUNE, a 10A/1200V SiC Mosfet. The kit includes a 60x55mm demonstration board with the half-bridge and the full documentation. Cissoid www.cissoid.com 64GB solid state drive on a secure chip With its second generation of highly secure 64 gigabyte solid state drive (SSD), Microsemi Corporation aims to address embedded designers’ concern about security threats and fraudulent firmware repurposing.Packaged in a 32x28mm ball grid array package, the 64GB SSD chip features a unique factory firmware lockdown technology to prevent covert firmware repurposing.The self-encrypting drive (through hardware-based AES-256 XTS encryption) delivers multiple key management methods and advanced security features based on the company’s proven Microsemi Armor III processor technology. For sensitive applications, the encryption key can be erased in less than 30 milliseconds and a second security layer can be activated to erase the entire storage media in less than 10 seconds, virtually rendering data forensically unrecoverable. Microsemi www.microsemi.com Fast charge developers kit speeds ultrathin supercapacitor prototyping Paper Battery Company, developer of a supercapacitorbased energy storage and battery enhancement technology, has released a Fast Charge Developers Kit for the company’s PowerResponder product line. The kit enables product designers to incorporate fast charging PowerResponder cells in their products allowing them to prototype a variety of input charging devices and protocols. With the Fast Charge Developers Kit, PowerResponder cells can be fully charged in less than five minutes. A ‘charge in minutes to run for hours’ capability is attractive for applications such as power tools, toys, Bluetooth headphones, medical and industrial handheld devices and game controllers, where intermittent use cycles allow for rapid recharge in between uses. Charging of lithium batteries (the company notes) is slow, needing hours even for small batteries, and fast charging is limited because of safety issues. The PowerResponder product line claims to have a much higher energy density than traditional supercapacitors, and can charge in minutes with none of the safety risks of lithium batteries. Power- Responders can be used in parallel with lithium batteries in external packs to enhance the charging rates and can also replace the lithium batteries in some cases. The Power- Responder cell could replace the lithium battery pack in the external power case sold for smartphones today, and provide two hours of talk time extension in two minutes of charging the external power case.
