Analog Devices
Analog Devices Inc. introduced the AD9226, a 12-bit, 65 MSPS analog-to-digital converter designed to increase data rates and enable direct intermediate frequency-sampling architectures for communications applications, including next-generation cellular base station and software radio applications. Analog Devices said the key to the AD9226 is its ability to digitize wideband signals with effective number of bits performance greater than 11 bits. In addition, the AD9226 dissipates 475 milliwatts of power from a +5 volt single supply, includes a 750 MHz full-power input bandwidth and is pin-compatible with the AD922X family of products and on-chip sample/hold amplifier. According to the company, a single converter allows IF transceivers to be re-programmed immediately to accommodate multiple modulation formats, reducing complex hardware requirements. The AD9226 is available in either 28-lead shrink small outline or 48-lead LQFP packages. (781) 329-4700.
Tellabs
Tellabs unveiled its Verity 3100 system, a high-density T1 and E1 echo control and voice-quality enhancement solution designed to help digital wireless and long-distance service providers improve voice quality and enhance network performance. Tellabs said the system provides optimal call quality and dependable data transmission over T1 and E1 trunk lines, while using less floor space to help carriers improve network efficiency, installation time and operating costs. The Verity 3100 system incorporates Tellabs VOE enhancements for processing 64 T1 and E1 network interfaces in a 19-inch American National Standards Institute shelf system. In addition to removing hybrid echo caused by electrical coupling at 2wire-to-4wire conversion points in the public switched telephone network, optional voice-quality enhancements are available to further enhance system performance for wireline and wireless carriers. According to Tellabs, the system’s level control optimizes speech levels by automatically compensating for extremely high or low audio levels that may be present at network interfaces. Also, Tellabs acoustic control is designed to provide protection from acoustic echo generated in wireless handsets, while Tellabs noise reduction reduces the background noise typically found in wireless environments. Tellabs also unveiled its Focus LX system, a multi-purpose synchronous digital hierarchy multiplexer with integrated cross-connects, designed to help service providers design a more efficient and flexible communications network to transport voice and data. The system offers add and drop multiplexing directly from 2.5 gigabits per second to 2 Megabits per second, and is designed to handle standard electrical and optical synchronous digital hierarchy, plesiochronous digital hierarchy and ATM interfaces. In addition, its adaptive pointer filtration and resynchronization capabilities provide GSM operators with a low-jitter, 2 Mbps data line for direct base transceiver station synchronization. Tellabs said the system can be deployed in all parts of a transport or access network, with its main strength lying in regional and metropolitan networks, where operators can use its cross-connect functionality to enhance network efficiency.
