Highly Integrated Wireless Single Chip Combines Bluetooth, eGPS, and FM Tx/Rx

(Top News, 5 Jun 2008)

CSR has launched its seventh generation BlueCore silicon—the BlueCore7—which is said to be the world's first device integrating Bluetooth v2.1+EDR, Bluetooth low energy, eGPS (enhanced Global Positioning System), and FM transmit and receive technologies on a single chip. CSR's BlueCore7 significantly reduces the power, size, cost and complexity of adding multiple radios into a mobile phone.

CSR has integrated Bluetooth low energy, eGPS and FM Tx and Rx technologies into BlueCore7 alongside an enhanced Bluetooth v2.1 + EDR radio, which delivers +10dBm Tx and -91dBm Rx. These enhancements help BlueCore7 to extend the overall range and across-body performance to provide better audio quality. In addition, BlueCore7 includes CSR's proprietary AuriStream voice CODEC, which produces the quality of a fixed line call, when using a Bluetooth connection, and is capable of a 30 percent reduction in power consumption. Inbuilt speaker drivers also allow users to connect headphones directly to the device.

BlueCore7 allows the Bluetooth and FM radios to work without interference, either independently or together to allow users to stream FM radio from a handset to a pair of Bluetooth headphones. CSR's FM receiver boasts -110dBm of sensitivity, securing high quality FM reception even in difficult environments. To overcome the challenges of using a handsets internal FM antenna, the FM transmitter has a uniquely high maximum output power of +4.5dBm.
