Analog Devices has unveiled a new DSP equipped with Layer 1 software that together are claimed to reduce system costs of 3G infrastructure equipment by up to 50%.
Analog Devices has unveiled a new DSP equipped with Layer 1 software that together are claimed to reduce system costs of 3G infrastructure equipment by up to 50% As the only DSP solution with the performance to enable an "all software" approach, ADI's TigerSHARC ADSP-TS101S is better equipped to address manufacturer's needs for flexibility, high performance, reduced bill of materials cost and added capacity than the traditional hardware approach that relies heavily on DSP plus ASICs and FPGAs

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
In addition to high performance and significant bill of materials savings, TigerSHARC is the only DSP solution that allows for quick migration between major third-generation modes that will be deployed in different regions of the world including WCDMA/UMTS, cdma2000 and TDS-CDMA.
As these third-generation standards evolve or new basestation features are required, TigerSHARC's 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.

Combined two-chip solution can reduce the active component count by 60% within a radio design, providing considerable board area and bill of material savings.
TigerSHARC also eliminates the cost of external memory and ASICs or FPGAs.
The TigerSHARC DSP has both the processing and I/O throughput necessary for both the chip rate and symbol rate tasks that are required to handle voice and data channels respectively without the need for support from multiple FPGAs or ASICs.
"Analog Devices has debunked the assertion that fixed function hardware solutions are best and only option for chip-rate processing in basestation systems.
TigerSHARC is a giant leap forward for third-generation wireless services and an important addition to our DSP family", said Brian McAloon, group vice president and general manager, DSP and System Products, Analog Devices.
"The challenges faced by wireless equipment manufacturers in delivering third generation services are well known.
Certainly the most significant challenges include the performance, flexibility and cost of supporting infrastructure.
Since TigerSHARC was designed with these challenges in mind, it delivers unparalleled performance with significant system cost savings, thereby helping to eliminate risk and to expedite the deployment of third generation cellular".
The ADSP-TS101S is the first TigerSHARC DSP to implement chip-rate and symbol-rate optimised instructions.
Analog Devices added these instructions after extensive development with base station customers.
At 180MHz, 6Mbit of internal memory, and direct multiprocessing support, the ADSP-TS101S is available now and shipping to customers.
The ADSP-TS101S is supported by a broad range of third party companies, including Delphi Communication Systems, Enea OSE, PA Consulting, Plexus, Torracomm and Transtech.
