General Description
Based on _äìÉ`çêÉRJjìäíáãÉÇá~=olj=nck, the
_äìÉqìåÉë=olj=nck integrates a Bluetooth radio,
baseband, DSP, high-quality audio codec, SMPS,
LDO and a battery charger for minimal BOM,
component count and PCB area.
BlueTunes ROM QFN uses advanced DSP features
for the latest stereo enhancements and to improve
audio quality, including SBC and MP3 decoder,
support for FastStream (low-latency codec) and
5‑band EQ.

Applications
Stereo headset solution with support for echo and
noise reduction
Wireless stereo speakers
BlueTunes ROM QFN includes as standard cVc dual
and single microphone algorithms for echo and noise
suppression.
cVc dual-microphone algorithm can provide >30dB of
noise suppression in both stationary and dynamic
noise conditions such as; babble, road, music and
competing voices. In addition an acoustic echo
canceller is now integrated into the cVc dual-
microphone solution, further enhancing the far-end
user experience.
A cVc single-microphone provides full-duplex echo
cancellation and a 10dB stationary noise suppressor.
BlueTunes ROM QFN includes secure simple pairing,
which greatly simplifies the pairing process, making it
even easier to use a Bluetooth headset.
