Single Chipset Supports All Major Cellular Standards
TelASIC Communications has announced the BaseFlex chipset, the world's first cost-effective wideband radio chipset to support all major cellular air interface standards, including GSM, GPRS, EDGE, IS-95 CDMA, WCDMA, cdma2000, and North American TDMA. The heart of the BaseFlex chipset is the company's high-performance IF sampling data converter technology, which reduces up- and down-conversion to a single stage, simplifying RF front-end complexity. The chipset delivers instantaneous bandwidth sufficient to cover any licensed commercial radio band up to 75MHz, enabling a powerful wideband radio architecture that can process multiple 2G, 2.5G, 3G and future wireless standards at the same time, within the same footprint as today's single-carrier, narrowband architectures. A multi-channel, fully programmable digital tuner completes the chipset.
Tony Giraudo, president and CEO of TelASIC, explained, "The BaseFlex chipset embodies the unique value proposition that TelASIC brings to developers of base station hardware. The combination of data converters and our fully programmable tuner delivers the wideband radio architecture that allows base station designers to build a truly universal base station platform that produces both immediate and long-term product portfolio benefits."
The BaseFlex architecture complements industry organizations that support open radio interfaces, including the Common Public Radio Interface (CPRI), which aims to define a publicly available specification for the key internal interface of radio base stations, and the Open Base Station Architecture Interface (OBSAI), which focuses on open specifications for certain parts of the base station's internal architecture and key interfaces.
The chipset consists of the TC1410, a 14-bit, 240 MSPS analog-to-digital converter, the TC4000, a multi-channel programmable tuner, and the TC2400, a 14- bit, 480 MSPS digital-to-analog converter. TelASIC's integrated circuits are implemented in IBM's SiGE Bi-CMOS and CMOS process technologies, which contribute to the excellent performance characteristics of each chip in the chipset."
