BLUETOOTH® 2.0 EDR WIRELESS AUDIO PROCESSOR
The BCM2037 wireless audio processor supports the Bluetooth 2.0 specification, with EDR technology enabling peak data rates of 3 Mbps, while providing full backward compatibility to Bluetooth 1.2 and Bluetooth 1.1 specifications. High integration with low-power operation make this family of chips ideal for incorporation into high volume, battery-operated wireless stereo and wireless mono consumer audio applications. Used in conjunction with a high quality external stereo codec, the BCM2037 solution delivers end-to-end streaming digital stereo at near CD audio quality. In addition, support for the remote control profile (AVRCP) allows a stereo headset to control a variety of remote music sources.
