ROM-based silicon finds home in Bluetooth SiP
AvantWave's Bluetooth v2.0 + EDR (Enhanced datarate) module uses CSR's BlueCore4-ROM silicon to achieve wireless datarates up to 3Mbit/s.
The headset also benefits from the newly ratified HFP1.5 Bluetooth profile improving overall voice quality.
By implementing BlueCore4-ROM, Nokia reduced the number of external components and a quick time to market was achieved.
Following a stylish and minimalist design, the Nokia BH-800 Bluetooth headset weighs only 9g and has a standby time of up to 160 hours.

WiFi and Bluetooth chosen for phone
CSR's intelligent RF design ensures trouble-free WiFi, Bluetooth and GSM/GPRS co-existence.
The headset features three main buttons positioned at the back of the device to handle calls as well as support voice recognition capabilities.
This enables the user to make and receive phone calls without the need for any further interaction with the mobile device.
The first Nokia headset to support Bluetooth v2.0+EDR, the Nokia BH-800 Bluetooth headset employs CSR's BlueCore4-ROM single chip radio and baseband IC.
It can deliver datarates up to three-times faster than current v1.2 Bluetooth devices and lower power consumption.
BlueCore4-ROM is backwards compatible with existing Bluetooth v1.1 and v1.2, meaning the Nokia BH-800 Bluetooth headset can be used with a host of compatible Bluetooth devices.
The inclusion of CSR's on-chip Bluetooth software stack provides a fully compliant Bluetooth system for voice communications.
BlueCore4 also incorporates auto-calibration and built-in self-test (BIST) routines to simplify development, type approval and production tests.
The Nokia BH-800 Bluetooth headset also implements the new HFP1.5 Bluetooth profile ratified by the Bluetooth Special Interest Group (SIG) in 2005.
The new Bluetooth profile, designed for headsets and handsfree calling, enhances overall voice quality and connection reliability.
The profile allows two voice packets to be sent at the same time, which means that there is a much lower chance of a packet being dropped compared with previous HFP Bluetooth specifications.
HFP1.5 also enables the effective implementation of eSCO (enhanced Synchronous Connection Orientated) channels, originally introduced with v1.2 of the Bluetooth specification.
Razvan Olosu, Vice President, Enhancements, Nokia, said: "The Nokia BH-800 Bluetooth headset is our first Bluetooth headset to feature Bluetooth v2.0+EDR and is designed to represent our 'culture of mobility'".
"In order to achieve the highest standard of connectivity, the choice of a Bluetooth collaborator was simple".
"CSR provided us with support and expertise in order to design a small headset with the most advanced technology and highest level of voice quality".
Gordon Petrie, VP, Sales Europe for CSR commented: "Designers and manufacturers are constantly faced with the problem of differentiating their product offerings in a highly competitive market".
"Nokia's choice to implement Bluetooth v2.0+EDR and BlueCore4 technology differentiates the Nokia BH-800 Bluetooth headset from other mono headsets by using the most current technology and achieving the highest levels of voice quality".
"CSR will continue to lend its support and expertise in wireless technologies to help device manufacturers achieve this high level of innovation and function".
