TI Unveils Revolutionary Digital RF Processor Architecture

The new chip design from TI gives hardware manufacturers more flexibility by reducing the number of components required for RF. The Digital RF Processor (DRP) has already been integrated successfully into GSM/GPRS handsets by TI’s R&D lab. This will cut power consumption from products, and also allow more room when designing to include other components such as; larger color displays, higher quality digital cameras, integrated GPS, WLAN, and Bluetooth. The DRP will also support RF enhancements through software rather than system or IC redesign.

TEXAS INSTRUMENTS DETAILS REVOLUTIONARY DIGITAL RF ARCHITECTURE, DRIVES DOWN WIRELESS POWER CONSUMPTION, CHIP COUNT

Digital RF Processing Takes System Integration to New Heights


Texas Instruments announced details of a radical new approach to wireless chip design that applies digital technology to greatly simplify radio frequency (RF) processing and dramatically cut the cost and power consumption of transmitting and receiving information wirelessly. The Digital RF Processor (DRP) architecture has been successfully integrated on two Bluetooth products, as well as a GSM / GPRS digital transceiver in TI´s lab. As mobile wireless products gain color displays, cameras, GPS location technology, local area networking capability and application processors to support digital audio and video, games, and PDA applications, board space and battery life can be greatly extended by the DRP design. At the prestigious International Solid State Circuits Conference (ISSCC) this week researchers from TI are presenting details of how DRP can reduce power consumption, die area and system board space by up to 50% over traditional analog RF designs.

“The processing of radio signals with digital logic can significantly shift the paradigm for embedding wireless communications by making it easier to implement and to scale,” said Dr. Hans Stork, TI’s chief technology officer. “With DRP, TI is leading the industry toward a future where wireless modules can be integrated into any kind of product, and provide the user with seamless access to a variety of network connections.”

Working GSM / GPRS Silicon
TI previously announced it will sample to customers this year a highly integrated, single chip GSM / GPRS product integrating the DRP design using TI´s 90nm process technology. The GSM / GPRS version of the DRP architecture has already proven fully functional on engineering development silicon now in TI´s lab. TI has one single chip Bluetooth product in production today with the DRP design, the BRF6100, and another sampling, the BRF6150.

“TI’s DRP architecture brings together the company’s signal processing expertise and in-house process technology in a fresh approach to RF processing,” said Allen Nogee, principal analyst, wireless component technology, In-Stat/MDR. “By incorporating RF functions digitally, TI provides the potential for modular radio configurations that address new applications and begin leading the industry toward software defined radio designs.”

A Revolutionary Approach

The Digital RF Processor technology combines TI´s years of signal processing architecture expertise with advanced semiconductor manufacturing capability to perform analog functions with low power, digital CMOS logic. Since large blocks of CMOS logic can now operate at multi-GHz frequencies, sampled-data processing techniques, switched-capacitor filters, oversampling converters, and digital signal processors can take over the role of analog amplifiers, filters, and mixers. Rather than an inefficient implementation of analog blocks in a digital process technology, with the DRP the analog signal is oversampled and processed in the digital domain. Since radio signals at the antenna are always analog, a small amount of analog processing is included in the DRP between the input and the first sampling function. Once in the sampled-data domain, digital signal processing takes over.

The RF section of a cell phone can occupy up to 50 percent of the printed circuit board, space that is required for today’s advanced feature sets. Color displays, cameras, GPS location technology, Bluetooth personal area networking, and WLAN connectivity for high-speed local-area data access, as well as application processors and additional memory to support digital audio and video, games, and PDA applications, are increasingly common. In addition to reducing the number of components required to implement RF, a digital design scales readily with Moore’s law and enables simple modification of key RF parameters to enhance performance through software rather than system or IC redesign.
