CSR has launched BlueVox DSP, a low-cost Bluetooth mono headset design with enhanced DSP-based Clear Voice Capture (CVC) echo and noise cancellation technology.

According to CSR, BlueVox DSP is the world's first ROM-based product with an integrated DSP coprocessor. It features AuriStream, CSR's low power voice codec for high-quality voice calls that offers a 30 percent reduction in power consumption compared with standard Bluetooth voice transmission methods, the company said.

With a BOM of $6, CSR has designed BlueVox DSP with a rich feature set that includes single and dual microphone noise suppression and support for simultaneous connection to two devices.

BlueVox DSP is based on CSR's BlueCore5-Multimedia platform, which features an audio codec with a signal-to-noise ratio of -95dB. The radio transmits at 8dBm and receives at -90dBm, which eliminates any interference and enhances range when taking a call.BlueVox DSP supports v2.1 +EDR of the Bluetooth specification. The BlueVox DSP features a compact 4-layer PCB reference design and is available in both 8mm x 8mm QFN and compact 7mm x 7mm BGA packages.
