Texas Instruments Inc. has launched a family of DSPs designed for the rapid development of femtocell solutions at the Femtocells World Summit.

The DSP family comes with a full portfolio of complementary analog solutions, support for Linux, and software solutions from TI third parties, continuous computing and mimoOn. Targeting HSPA applications, the DSPS enable low-cost, fully programmable solutions that will let OEMs offer reliable and adaptable femtocell products to market.

Software reference designs are available from Continuous Computing and mimoOn that provides customers with software for Layer 1, 2 and 3 wireless protocol processing. The femtocell products to be created are expected to provide increased wireless connectivity for streaming video files, interactive gaming, music sharing and other bandwidth-intense multimedia tasks.

TI's femtocell product family includes the TMS320TCI6485 with two high-performance 850MHz C64x+ DSP cores delivering 1.7GHz of overall performance for residential femtocell applications, and the TMS320TCI6489 which includes three 850MHz C64x DSPs delivering 2.55GHz of performance for enterprise or "super femto" applications. Scaling to meet the varied global requirements of the residential and enterprise market segments, TI's TCI6485 supports up to eight users while the TCI6489 supports up to 32 users. The entire product family is compatible with all major 2G/3G and 4G systems including GSM, CDMA, W-CDMA, TD-SCDMA, WiMAX and LTE, and furthermore, is code compatible with other TI DSPs for the wireless infrastructure market, where any previous investments in macro or pico base stations can be reused. TI's longstanding incumbency in the wireless infrastructure space combined with its robust DSP solutions developed specifically for the femtocell market allow OEMs to develop products for this emerging market with confidence.

Both the TCI6485 and TCI6489 will sample in Q3 09 and start production in Q4 09.
