CSR ADR : CSR's SiRFstarIVTM is Chosen for Timex® Ironman® Run Trainer? With GPS

CSR SiRFstarIVTM enables low-power, high-precision, body-worn GPS location, pace and distance tracking for runners in the Timex® Ironman® Run Trainer? System

2012 International CES - CSR plc (LSE:CSR) (NASDAQ:CSRE) today announced Timex, a leading U.S. watch manufacturer, has incorporated CSR's powerful SiRFstarIV^TM GPS technology in its recently announced Timex® Ironman® Run Trainer? product.

SiRFstarIV combined with the SiRFInstantFix^TM technology gives the new high-performance training watch a reduced "time-to-first-fix," enabling runners to begin their run with minimal delay. SiRFstarIV performance gives users location, pace and distance tracking throughout their workout, even in challenging environments, from crowded urban canyons to dense forests and uneven elevations. SiRFstarIV's low-power consumption means long battery life for the Ironman Run Trainer -- eight hours in full GPS mode.

"The Ironman Run Trainer with GPS is another indication of how dedicated Timex is to giving athletes, trainers and fitness enthusiasts the tools they need to improve and simplify their training," said Paul Williamson, Health and Fitness product marketing manager of CSR. "We have been extremely pleased for the opportunity to work together on this project, and that CSR's SiRFstarIV was able to deliver the fast fix, high-sensitivity, and low-power advantages Timex customers have come to expect."

SiRFstarIV is optimised for size and battery constrained applications. Manufacturers benefit from greatly-improved power consumption, small package size, ease of integration and low-cost implementation. SiRFInstantFix technology eliminates the wait typically associated with obtaining satellite broadcast GPS data needed to get a fix. This results in improved start-up performance even in weak signal environments with start-up times of ten seconds or less.

"CSR has been a true partner in helping us realise our vision for the Timex Ironman Run Trainer with GPS," said Heberto Calves, vice president of marketing at Timex. "SiRFstarIV gave us the ability to meet all of our location-related goals for the product, and their support of our in-house design team was invaluable."
