Lucent Technologies Introduces Cost-Saving Converter Chip For Wireless Base Stations PR Newswire - May 13, 1998 08:23 ALLENTOWN, Pa., May 13 /PRNewswire/ -- Lucent Technologies' Microelectronics Group today introduced the first analog-to-digital (A-to-D) converter chip for wireless base station applications that incorporates the dither function. This technical advance means base station manufacturers can save approximately $10 per converter chip using Lucent's technology compared with others on the market. Dither reduces distortion and extraneous signals up to 100 decibels below maximum signal levels, thereby making it easier for the converter chip to process weak incoming signals in the presence of strong interference signals. "Other A-to-D converter manufacturers have to use off-chip dither for wireless base station applications," said Aaron Fisher, general manager of wireless integrated circuits with Lucent's Microelectronics Group. "Lucent is the first company to put the dither inside the converter, which translates to significant cost savings. We're charging approximately the same price for an A-to-D converter with dither on chip as others are for the A-to-D converter using off-chip dither." Lucent's new CSP1152A chip has a 65 megasamples per second sampling rate, a 14-bit resolution, and a maximum of 1 gigahertz of bandwidth. The chip can be used for Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), and Time Division Multiple Access (TDMA) wireless standards. In addition to the on-chip dither functionality and overall high-performance design, the converter has a low-voltage differential signaling (LVDS) output, which is a low-noise, high-speed electrical interface that moves data from the converter chip to a digital signal processor (DSP) chip. This interface enhances the quality and reliability of the signal transmission because the signals are transmitted at a low noise level, providing little or no degradation to the sensitive signals on the circuit board. The chip uses Complementary Metal Oxide Semiconductor (CMOS) process technology, which enables volume production capabilities in shorter time frames than other process technologies and allows for future integration paths with digital electronics. Lucent is currently sampling the CSP1152A and expects to start shipping production quantities in the fourth quarter of this year. The chip will be priced at $35 in quantities of 50,000 or more.
