Multi-Carrier Mixed Signal Processor
Texas Instruments Inc. (TI) introduces a mixed signal receive processor for 3G base stations and fixed wireless communication devices. The AFE8406 multi-carrier chip integrates a dual 14-bit 85 MS/s (mega samples per second) A/D converter (ADC) and sixteen channels of programmable digital down conversion (DDC) into a single device. This multi-channel communication signal processor offers increased density, resulting in lower costs for systems supporting a range of 3G standards. TI's AFE8406 can be configured to support up to four-carrier UMTS, eight-carrier CDMA or eight-carrier TD-SCDMA diversity receivers. It delivers good intermediate frequency (IF) performance with low noise to enable multi carrier operations. At an input frequency of 140 MHz, the device delivers signal-to-noise ratio (SNR) of > 68 dB, and spurious free dynamic range (SFDR) of > 70 dBc. For developers using the AFE8406, the company provides an evaluation module (EVM) for easy integration of the device into wireless infrastructure base stations and other targeted applications. The EVM is complemented with the easy to use GC Studio software for data analysis.
