Digital Signal Processor for 3G Base Stations
In addition to high performance and significant bill of materials savings, the new TigerSHARC DSP is the only fully-programmable solution that allows for quick migration between major 3G modes that will be deployed in different regions of the world including WCDMA/UMTS, cdma2000 and TDS-CDMA. As these 3G standards evolve or new base station features are required, a TigerSHARC DSP-based approach provides added flexibility because the intellectual property resides in the software, not in fixed function blocks. The result is fast time-to-market for upgrades or new products.
The TigerSHARC DSP also eliminates the cost of external memory and ASICs or FPGAs. The TigerSHARC DSP is a telecommunications-optimized, programmable device with the processing and data throughput performance to handle both the chip rate and symbol rate tasks required for voice and data channel processing.
The ADSP-TS101S is the first TigerSHARC DSP to implement chip-rate and symbol-rate optimized instructions. Analog Devices added these instructions after extensive development with base station customers. With 6 megabits of on-chip memory and direct multiprocessing support, the ADSP-TS101S is available and shipping to base station customers. The ADSP-TS101S is supported by a broad range of third party companies, including Delphi Communication Systems, OSE Systems, PA Consulting Group, Plexus Corporation, Toracomm, and Transtech DSP. ADI offers complete all-air-interfaces base station signal chain solutions, including analog RF and IF signal processing, data conversion, and digital signal processing. ADI's SoftCell multi-carrier transceiver chipset includes all the key functional blocks for implementing a software radio platform.
