OpenVPX(R) 40G Ethernet + InfiniBand(R) Switch Card

Curtiss-Wright Controls Defense Solutions (Ashburn, VA), a business group of Curtiss-Wright Controls, has introduced the newest member of its Fabric40(TM) family of extremely high-speed 40 Gbps OpenVPX™modules. The new VPX6-6802 Fabric40 Switch is the first rugged, high performance 6U OpenVPX (VITA 65) switch card to provide support for 10/20/40 Gigabit Ethernet (GbE) and SDR/DDR/QDR/FDR-10 InfiniBand®(IB) connectivity to OpenVPX™ systems. Systems built using the VPX6-6802 and complementary Curtiss-Wright Fabric40 system elements will deliver over 2x the performance of previous generation SRIO Gen-2-based systems and 4x the performance of 10 GbE-based systems. The fully rugged VPX6-6802 is available in air-, conduction-, and air flow-through (AFT)-cooled configurations. Designed for use with today’s highest speed switched fabrics, the board provides a combined Data Plane and Control Plane high-performance switch for 6U VPX systems.

Closed-Loop I2S Audio Amplifiers

Texas Instruments (TI) (Dallas, TX) has introduced a family of four digital-input, closed-loop I2S amplifiers for mid-power stereo audio applications including TVs, soundbars, portable docking stations, Bluetooth® speakers, and aftermarket automotive audio products. The TAS5760xx devices feature high switching frequency, allowing designers to use smaller output filter components to reduce overall solution size and bill of materials (BOM) cost. They stream 20W continuous power per channel without a heatsink, and deliver superior performance specifications, including THD+N of 0.03 percent at 1 W, crosstalk of -92 dB, and 66-uV idle channel noise.

MicroTCA Ecosystem

VadaTech (Henderson, NV) has released a complete ecosystem of boards and chassis in the MicroTCA architecture that is conduction-cooled. Designed for rugged applications, the products include air transport racks (ATR), MicroTCA carrier hubs (MCH), power modules, and advanced mezzanine cards. Compliant to MicroTCA.3 (Hardened Conduction-Cooled MicroTCA) specification, the boards and chassis come in various sizes and formats.

The MCH, which acts as a shelf controller, features a 400 MHz RISC CPU for high performance and low latency. The power modules provide true hot- swappability in a dual 10-36V input and outputs of up to 800W. They also have dual Intelligent Platform Management Interface (IPMI) and two banks of 256K flash for redundancy. Several of VadaTech’s advanced mezzanine cards (AMCs) are in the conduction-cooled format. The company is also able to modify standard AMCs to ruggedized versions with wedge locks.

XMC Controller/Adapter

Technobox, Inc. (West Berlin, NJ) has introduced a new SATA-based storage solution in its 6183 Dual CFast XMC Adapter. The 6183 accommodates two CFast devices – either the Type 1 or 2 – with one affixed to an on-board site and the other removable via the front panel port. Data movement between each CFast device and the internal 1X PCIe bus is controlled by a Silicon Image Sil3132 bridge. The bridge supports two SATA Gen2 interfaces at 3.0 GBytes/s.

On-board BIOS, loaded in flash memory, provides boot up configuration for the Sil3132. The bridge retrieves the stored configuration data via an I2C interface. Two LEDs on the front panel provide activity status for the front panel and onboard CFast cards. Another four LEDs on the card give an indication of activity for each device.

A retention mechanism is included to prevent accidental removal of the front panel device. The retainer also functions as an interlock for the 6183 hot swap feature. .

DDS Function Generator

Saelig Company, Inc. (Fairport, NY) has introduced the TG1006 - a DDS-based 1mHz to 10MHz function generator that, unlike other digital generators, can be operated over any frequency range using analog control in addition to numeric or spin-wheel frequency entry. The quasi-analog frequency control can rapidly sweep the frequency between preset limits, which is difficult to do with most digital function generators.

The TG1006 Function Generator can produce waveforms between 0.001Hz and 10MHz with a resolution of six digits, and with a one-year stability of better than 10ppm. Up to ten frequencies can also be stored in memory for preset test procedures. The output amplitude is variable between 5mV and 20V pk-pk from a source impedance of 50 ohms or 600 ohms. The LCD display shows frequency and amplitude or offset simultaneously. For accurate frequency selection, precise frequencies can be entered directly from the numeric keypad in Hz, kHz or MHz.

Embedded Radios

Specialized wireless transceivers and radio modems from Ritron (Carmel, IN)provide OEMs and Integrators with wireless connectivity and COTS convenience in a compact, cost-effective package. Direct modulation with low distortion and low group delay results in a low bit-error-rate (BER) for enhanced system integrity and reliability. The Swift Lock™ synthesizer-loading algorithm reduces unit turn-on-time to less than 10ms or high-speed data throughput, and Controlled Envelope™ keying reduces adjacent channel “keyclicks”, resulting in spectrum-friendly operation.

All models meet the 2013 FCC narrowband mandate. All components are placed on the top side of a single PCB for mechanical rigidity and increased protection against damage. Narrow band (12.5 kHz) and Very narrow Band (6.25 kHz) models available.
