CSR saw revenues jump by 32 per cent in the third quarter as its share of the Bluetooth chipset market passed the 50 per cent mark.

CSR has maintained its leadership in Bluetooth with approximately 60% of the total available design wins so far this year and the Board is confident that further significant growth will be achieved in 2007,” said company CEO John Scarisbrick.

While Bluetooth remains the Cambridge-based firm’s all-important market, it is conscious that future growth will come from other wireless products such as wireless LANs and voice-over-IP handsets.

In the summer demonstrated the broadening of its non-Bluetooth portfolio with the launch of its UniVox VoWiFi phone reference design, which is based on its UniFi Wi-Fi chip.

These new markets are likely to be more competitive with big name players such as Texas Instruments, Freescale and Broadcom very aggressive. So the market for Bluetooth silicon in mobiles, headsets and cars will continue to determine CSR’s success for some time ahead.

“Bluetooth is increasingly being designed into an ever more diversified range of products and encouragingly we have started to see significant design activity in the consumer segment which includes applications such as MP3 players,” said Scarisbrick. 

Q3 revenues of $214.1m generated operating profit of $51m, which was up 14% compared with the same period in 2005.
