TI Unveils Single-Chip Multi-Carrier Mixed Signal Processor For 3G Applications — Cormac @ 20:01
TI today introduced its most integrated, highest performance diversity mixed signal receive processor for 3G base stations and fixed wireless communication devices. TI's AFE8406 multi-carrier chip integrates a dual 14 bit 85 MSPS (mega samples per second) ADC and sixteen channels of programmable digital down conversion (DDC) into a single device. The multiple DDC channels allow a larger number of carriers per signal chain, translating to reduced implementation costs. TI's AFE8406 can be configured to support up to four-carrier UMTS, eight-carrier CDMA or eight-carrier TD-SCDMA diversity receivers. At an input frequency of 140 MHz, the device delivers SNR of greater than 68 dB, and spurious free dynamic range (SFDR) of greater than 70 dBc.
For developers using the AFE8406, TI 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 GC Studio software for data analysis.
The AFE8406 is available in a 484-pin 23 mm x 23 mm ball grid array (BGA) package. Samples are available now with projected production in 1Q 2006.
