Cellular baseband can evolve with
standards
Multimode baseband platform forms the basis of a next-generation software defined radio system to cater for the changing requirements of LTE.
NXP Semiconductors will demonstrate the world's first LTE/HSPA/UMTS/Edge/GPRS/GSM multimode baseband platform which forms the basis of a next-generation software defined radio (SDR) system solution at the Mobile World Congress in Barcelona Powered by NXP's EVP embedded vector processor, a powerful new digital signal processing core, the solution is capable of achieving data transfer rates of 150Mbit/s downlink and 50Mbit/s uplink and supports multimode capability to cope with evolving mobile standards, particularly challenging for the next generation of mobile terminal manufacturers

High security for smart card MCU family
Philips Semiconductors describes SmartMX as the world's first ultra-low-power cost-optimised high-performance family of smart card controller ICs.
The differentiating value of the EVP-based modem architecture is the ability to support multistandard baseband processing with negligible area and power penalties - a significant breakthrough from previous generations of baseband architectures.
Though the specifications for LTE are being finalised, NXP is able to implement preliminary specifications today and update the multimode baseband as the standard evolves.
Critical to this approach is the implementation of the highly parallel EVP to provide the computational resources for demanding MIMO and OFDM modem functionality.

Class D family provides single-chip audio
Philips Semiconductors has boosted the home audio market, launching a series of single-chip Class D audio amplifiers.
This software programmable platform will enable OEMs to develop their next-generation products quickly with on-the-fly changes to the core behaviour of the modem during the critical ramp-up phase of the technology, enabling faster time to market and better performance.
"This is the first cellular system solution to use NXP's breakthrough EVP technology to support the entire GSM family of standards, right through to LTE", says Marc Cetto, Executive Vice President and General Manager, Business Unit Mobile and Personal, NXP Semiconductors.
"The solution is fully compliant to the current draft of the 3GPP R8 standard, and was defined in close partnership with global operators, OEMs and infrastructure vendors".
"Using a software-defined radio approach, we can create silicon and system platforms that evolve as quickly as the industry does".
NXP has selected the first implementation of a multimode baseband processor to address the LTE market as it represents the exciting future of next-generation broadband mobility for consumers.
"NXP has fully committed to the long-term evolution of the 3GPP roadmap and is investing significantly in standardisation and industry-wide co-operation to realise the vision of a connected-everywhere future", adds Cetto.
LTE customers will benefit from an enhanced user experience as next-generation devices deliver ultrafast Internet browsing, streaming video services, multiplayer gaming and even full length HDTV films.
"LTE will usher in a new era of mobile connectivity, and provide consumers with the services and experiences they are used to from the Internet, while they are on-the-go".
"Multimedia content sharing and Web 2.0 services will be the drivers for next-generation handsets and a new breed of connected consumer electronics", says Cetto.
This technological breakthrough is targeting not only the handset market, but will also be optimised for next generation laptops, Internet tablets and a new breed of ultramobile PCs (UMPC).
