Acqiris USA has recently come to market with a 21-slot crate known as the CC121. It enables high-speed digitizer systems to be configured with up to 80 channels in a single, standard, 19-in.-wide, 9U-high instrumentation rack. Deploying a quad-channel digitizer module, the CC121 (at 1-GHz bandwidth) can operate 80 channels at a 1-GSample/s sampling rate. That includes 40 channels at 2 GSamples/s and 20 channels at 4 GSamples/s. This operational capability makes the crate ideal for the data-acquisition systems that require a high number of channels in the smallest possible space. Potential uses of this product include physics, astronomy, automated test equipment, and telecommunications applications in which system size and cost per channel need to be optimized.

The crate's patent-pending cooling system allows installed modules to run at an optimal, safe operating temperature. This aspect ensures a stable, uniform internal operating temperature with minimal variation. As a result, there is less drift in measurement precision and less frequent recalibration. Efficient operation is further provided by EMI shielding, which minimizes the effects of unwanted noise and interference. In addition, high-quality power supplies increase system reliability.

The CC121 crate is compatible with CompactPCI extension interfaces and embedded Pentium processor boards for modular "plug-and-play" applications. A variety of standard interfaces can be used to fully control the CC121 and connect it to any PC. A CompactPCI-PCI bridge connection can be made via copper or fiber-optic cables. In such instances, PCI-bus data-transfer speeds of up to 100 MBps can be achieved. Alternatively, standalone systems can be easily created with the installation of Acqiris' PC502—a 1-GHz, Pentium-based, single-slot controller with a 20-GB hard disk, Ethernet, and Windows-based operating system. The Ethernet port can be used to connect multiple crates together for applications that require more than 80 channels.

In addition to its high channel density, the CC121's single-rack design requires less cabling. The result is simplified installation and maintenance. Further simplification is achieved through the use of a unique rear-access design, which yields access to all system components whenever necessary.

Now available, the CC121 can be purchased for $9990 per unit. Delivery time is four weeks following the receipt of the order. For additional information on this product, go to the Web site: www.acqiris.com.

Taiyo Yuden (U.S.A.), Inc. has now begun the development and commercialization of module solutions for 5-GHz wireless-LAN (IEEE 802.11a) applications. Until this point, the company has been leveraging the market recognition and high-frequency technology that it obtained through its Bluetooth module research and development. Now, it has formally established a partnership with Resonext Communications, Inc. as the supplier for 802.11a chip sets. As a San Jose-based fabless semiconductor company, Resonext Communications develops complete end-to-end chip-set solutions. Resonext began introducing 802.11a chip sets this past fall.

The chip sets feature the True Zero-IF 5-GHz CMOS radio. This radio was specifically designed for reduced materials cost and low power consumption. It also boasts flexible media access control (MAC) to support differentiation and the evolving IEEE standards. In addition, it supports AccuChannel equalization technology. This technology delivers up to a 32% greater range for all data rates. As a result of this partnership, Taiyo Yuden has now begun developing and commercializing 802.11a modules with the new Resonext chip sets. The IEEE 802.11a wireless LAN operates in the 5-GHz band. It is expected to become widely integrated into various electronic appliances in the coming months.

In addition, Taiyo Yuden has announced that its efforts to develop high-speed wireless components and modules will not be limited to 802.11a technology. Rather, the company will be converging its materials; multi-layer, high-frequency design; and high-density mounting technology for use in the development of various solutions. These solutions will aim to simplify the process of adopting new wireless technology.
