Compression and security coprocessors target data analytics, storage and cloud security Providing leading-edge compression to remove or minimize costly I/O bottlenecks and enable maximum system throughput with minimum latency, Exar’s XR9200 Coprocessor family addresses the requirements of in high performance applications for the data analytics, storage, and cloud security markets. The XR9200’s hardwareaccelerated encryption and public key processing enables the secure infrastructure needed to support high transaction throughput and packet-per-second rate required by enterprise, cloud and web-based applications. The family of coprocessors offloads computationally intensive compression and security algorithms from a host CPU and matches the performance of hundreds of enterprise class x86 CPU cores at much lower power and cost. The chip supports 40Gbit/s of processing throughput with simultaneous compression, encryption and hashing, offering compression ratios comparable to Level 9 gzip. It supports 40,000 operations/s of RSA with 2048 bit keys. Other features include a PCI Express 3.0 host interface supporting 64Gbit/s of bandwidth with 8 lanes and a 40Gbit/s Interlaken interface for external FPGA connection. The device also allows single root I/O virtualization (SRIOV) with 128 virtual functions to support virtualized I/Os. It can implement gzip, zlib, Deflate, and eLZS, with support for a wide range of symmetric and asymmetric encryption algorithms. Exar www.exar.com Single- and three-phase EMC filters offer standard or very high noise attenuation The extensive range of low profile single-phase (RS series) and three-phase (RT series) filters from TDK-Lambda enables designers to combat potentially noisy disturbances in endsystem applications. Within the R series, a choice of single-stage or two-stage filters is available to provide standard or very high noise attenuation levels, from 150kHz up to 30MHz. In addition, high pulse attenuation is available on some models to prevent line spikes from entering or leaving the OEM equipment. The current ratings for the single-phase RS units range from 0.5A up to 300A, with line voltages up to 250Vac or 250Vdc and leakage currents of 1mA. Low leakage models are available with 10μA of leakage current at 250Vac, 60Hz. The three-phase RT series filters offer current ratings from 6A up to 1000A, with line voltages up to 500Vac or 500Vdc. The maximum leakage current is 2.5mA at 250Vac, 60Hz or 5mA at 500Vac, 60Hz. For ease of installation, many of the models can be specified with wire leads, lug terminals or captive screw terminals. A choice of either standard chassis or DIN Rail mounting is also available on many filter models rated up to 30A (with screw terminals). Single-phase RS filters are safety certified to UL1283, CSA C22.2 No. 8, and EN60939 (up to 30A). The operating temperature range is from -25°C to +85°C. TDK-Lambda www.uk.tdk-lambda.com/r-series 1.6x1.2x0.4mm crystal covers the 26 to 60MHz frequency range: 15ppm tolerance Raltron Electronics has released a new Model R1612 Microprocessor Crystal, a unit measuring only 1.6x1.2x0.4mm and suitable for automatic pick and place and reflow soldering. Covering a frequency range of 26MHz to 60MHz and available with room temperature frequency tolerances of 15ppm and 30ppm, the small crystal units have a 50% smaller footprint than most crystals on the market, claims manufacturer Raltron. Temperature stability ranges from 10ppm to 50ppm while the operating temperature ranges from -10°C to +60°C standard, to -20°C to +75°C extended. Sample turnaround is 4 weeks, while volume quantities can be delivered within 6 to 8 weeks. Raltron Electronics www.raltron.com Smart meter chip adds multi-standard OFDM powerline communications for M2M Italian smart meter chip designer Accent has added multistandard OFDM powerline communications to its ASMgrid2 family to support machine-to-machine (M2M) applications. The ASM220 uses the company’s field-proven SUNFXPLC silicon to support multiple leading standards such as G3-PLC, PRIME, ITU G.990x and IEEE P1901.2. The ASM220 targets the rapidly growing powerline communications (PLC) Smart Meter market as well as emerging M2M applications such as distribution automation, solar, building automation, and street lighting. The device tailors existing ASMgrid2 solutions primarily towards the communication as well as processing needs for many M2M applications. SUNFX-PLC is already incorporated in Accent’s ASM221 and which also recently completed G3-PLC interoperability testing, implements a hybrid hardware/software PLC modem as well as analog front end. An ARM Cortex-M3 serves as the processor backbone for the SUNFX-PLC modem with performance intensive blocks implemented in hardware. The ASM220 also implements a scalable SDRAM memory system with an ARM Cortex-M3 with 110+ DMIPS of performance for both application and communication processing, with 256KB/48KB of embedded Flash/SRAM and a 2 MB package option. The ASM220 fully leverages the ASMgrid2 solution platform, which includes communications stacks, development boards, and reference designs. The system is compliant with CENELEC, FCC, and ARIB bands of operation from 10 kHz to 490 kHz and includes an integrated PLC AFE for low system bill-of-materials.
