CSR's BlueVOX-QFN is the only Bluetooth headset chip available that enables the use of a low-cost, two-layer, single-sided PCB instead of the conventional four or more layers.

The BlueVOX-QFN plus all necessary components for a Bluetooth mono headset will cost OEMs only $6 for the electronic BOM (eBOM)which means that Bluetooth headsets can be produced at a fraction of current costs.

$6 eBOM
The total eBOM of $6 covers cost for the silicon, as well as a lithium battery, PCB, microphone and speaker, plus all additional electronic components.

CSR's BlueVOX-QFN is available today, and headsets using BlueVOX-QFN are expected to be on the market by Q2 2007.

With a powerful +5.5dBm transmitter and a sensitive -88dBm receiver, the new device offers superior RF performance to any announced Bluetooth headset solution.

This performance advantage means that headsets designed using the BlueVOX-QFN chip will more reliably maintain connection when there is no line of sight between the headset and the phone.

10hrs battery life
Power consumption is also better than any announced headset solution, with a small, light weight battery lasting up to 10hrs between charges. The device's internal battery charger uses an advanced charging algorithm that includes the measured ambient temperature to prevent overcharging. In addition, the charging circuitry can also support low cost NiMH batteries.

CSR has launched BlueVOX-QFN with an accompanying reference design that simplifies the task of creating a high-quality, low-cost headset. The reference design includes schematic, layout, BOM and Gerber files.
