Stereo Headset Solution
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.
inputs. A USB plug-and-play adapter can be implemented without using
a codec by using the built-in USB interface on the BCM2037.
The BCM2037 has sufficient processing performance to simultaneously
manage the user interface, maintain full Bluetooth protocol stack
operation, and execute key audio algorithms. This high performance is
enabled by a 32-bit ARM7® CPU with high-peak clock speeds and deep
on-chip memory, allowing zero-wait-state execution of computationally
intensive audio algorithms.
Key algorithms are supported by application-specific hardware
accelerators, further increasing BCM2037 computational capabilities,
while reducing system power consumption. These powerful features
eliminate the need for a separate external DSP, reducing the bill of
materials, power consumption, and total footprint.
The BCM2037 is capable of transmitting using EDR permitting lower
power, increased robustness, and lower latency as compared to
Bluetooth 1.2-based audio solutions. Additional bandwidth of EDR
enables complex Bluetooth environments with multiple active Bluetooth
devices and provides support for multiple simultaneous stereo links.
The BCM2037 can be bundled with ZSound, a complete production-
ready, qualified software package including starting applications,
Bluetooth profiles, and protocol stack that facilitates time-to-market.
This complete solution makes the BCM2037 an excellent choice for a
wide variety of wireless audio applications.
A stereo headset combining mono and stereo functions can be
accomplished by combining the BCM2037 with a codec that has stereo
output and MIC input. An audio gateway can be implemented by
combining the BCM2037 with a codec that has stereo outputs and stereo
