CSR announced the launch of its sixth-generation BlueCore Bluetooth chip. BlueCore6 offers industry-leading radio performance and low power consumption, and fully supports the latest Bluetooth specification (v2.1+EDR). BlueCore6 includes CSR's AuriStreamTM technology, which is a huge breakthrough in the way Bluetooth handles voice transmissions; AuriStream technology provides higher voice quality, and BlueCore6-ROM consumes less power than standard Bluetooth voice transmission methods. 40%. BlueCore6 will begin mass production in January 2008.
CSR further enhances RF performance and provides BlueCore6 with best-in-class Bluetooth coverage without the need for an external power amplifier. Compared to BlueCore4, BlueCore6's maximum allowable power loss standard value improves overall by 11dB (Tx input power +4dBm, Rx input power -7dBm), making BlueCore6 the most efficient Bluetooth radio in the industry and helping to improve the overall body operation For example, a connection between a Bluetooth headset and a mobile phone carried by the user is established. The BlueCore6-ROM is smaller than other brands of Bluetooth chips and is packaged using CSR's tested and validated wafer-level CSPs.
Voice is still an important application area of Bluetooth technology. Users constantly demand higher voice quality and longer battery life. CSR's BlueCore4 is the world's leading Bluetooth chip. The currently launched BlueCore6 has all of its features and has made important improvements in voice quality and power requirements.
Fiona Thomson, senior analyst at IMS Research, a UK market research company, said: “Our research has found that consumers expect to have products with high performance and low power consumption, such as CSR's BlueCore6. CSR continues to introduce new products for Bluetooth products. Not only does it benefit consumers, but it also strengthens CSR's leadership in mobile phones and headsets, making it a preferred choice for manufacturers."
Traditionally, Bluetooth has relied on a Continuous Variable Slope Delta Modulation (CVSD) coding scheme to deliver voice over synchronous connection-oriented (SCO) links. CVSD is a fairly simple binary encoding scheme. We chose this solution because it is very reliable and error-proof. However, SCO does not allow retransmission of erroneous data packets. However, after the release of Bluetooth specification v1.2, eSCO can implement retransmission. Through the AuriStream technology, CSR introduced Adaptive Differential Pulse Code Modulation (ADPCM) as an enhanced speech coding method that can perform exactly the same function at half the rate of CVSD (ADPCM scan rate is 32Kbps, while CVSD is 64Kbps) saves half of the Bluetooth power consumption of your phone. ADPCM performs more accurately and provides higher voice quality. CSR's AuriStream technology raises the user's average opinion score for voice quality from CVSD's 2.41 to the current 4.14, enabling Bluetooth connectivity to the level of fixed-line voice.
CSR has adopted a variety of technologies on BlueCore6 that have greatly reduced the power consumption of Bluetooth or main devices. CSR reduced standby power consumption and adjusted the way Bluetooth devices scan other devices. On average, standby power consumes more than half of the overall power consumption in a Bluetooth system.
CSR's BlueCore6 uses two new scanning modes: conditional scanning and random scanning. By combining these technologies with BlueCore6-ROM, CSR saved 86% of Bluetooth power consumption in scanning mode.
When performing a condition scan, BlueCore only wakes up a minimum number of radios to perform a quick scan of 2.4 GHz band activity. If there is activity, it will initiate a formal Bluetooth paging scan/paging; if no activity is found, the radio will remain dormant.
CSR's random scan mode synchronizes the BlueCore6-ROM's periodic wake-up procedure with the attached baseband device so that VCTXO does not always wake up during the Bluetooth scan cycle. The Bluetooth chip typically shares a VCTXO with the mobile phone host system to minimize the use of other components and save the power consumption of the mobile phone system.
CSR CEO John Scarisbrick said: "BlueCore6 is CSR's most outstanding Bluetooth chip, and it provides new technology that is unique to any of our previous generations of products. BlueCore6 is ahead of any similar technology on the market today. This fully demonstrates that CSR continues to maintain its leading position in wireless innovation,” said Mr. Scarisbrick: “The major top mobile phone and headset manufacturers have expressed great interest in our BlueCore6 products.”
