A complete modem design

UK-based TTPCom has launched a complete baseband modem design aimed at enabling chip manufacturers to incorporate cellular communications technology into their products.

UK-based TTPCom has launched a complete baseband modem design aimed at enabling chip manufacturers to incorporate cellular communications technology into their products.

The CBEmacro design,as it is called, enables manufacturers, such as those developing application and video processors, to add wireless functionality to their technology within just one year, without making substantial investments in research and development.

The ‘macro’ implementation of TTPCom’s proven Cellular Baseband Engine (CBE) design was developed as a result of the company’s view that mobile handsets are becoming increasingly differentiated by multimedia technologies and high-end applications capabilities, rather than the underlying modem. TTPCom’s CBEmacro enables handset technology suppliers to focus on these important differentiators by providing the essential modem peripheral as a black-box, system-on-chip component. CBEmacro is designed to be silicon process independent, enabling licensees to use a silicon foundry of choice.

The CBEmacro hardware design includes the DSP and micro controller cores, memory sub-system and dedicated GSM, GPRS and EDGE logic. CBEmacro also includes a complete suite of physical layer and protocol software derived from TTPCom’s field proven designs. Both standard IQ and DigRF radio interfaces are supported. The current version of CBEmacro fully supports GSM, GPRS and EDGE with a clear roadmap to dual system 3G and GSM.

‘We realised a while ago that application and video processors were becoming increasingly attractive to mobile handset manufacturers, who want to increase the quantity and quality of the applications without impacting on the standardised modem. We have developed and fully tested CBEmacro to enable chip vendors to simply and quickly add wireless connectivity to their highly differentiated products as a peripheral device’, said Julian Hildersley, Managing Director of TTPCom’s Silicon Business Unit.

TTPCom will be demonstrating its CBEmacro baseband hardware design in a single FPGA on stand 1914 at Expo Comm Wireless Japan 2004 in Tokyo from the 21st to the 23rd July.
