Broadcom adds two wireless headset Bluetooth chips

Tim Higgins

January 29, 2007

Broadcom today announced two new single-chip solutions aimed at wireless headset applications that support Bluetooth Version 2.0 with EDR. The duo support Broadcom's SmartAudio sound enhancement technology and are upgradeable to Bluetooth Version 2.1.

The BCM2047 is targeted at premium headset products and includes an integrated ARM AudioDE based digital signal processor for premium sound quality. The DSP can handle stereo SBC, MP3 and AAC compression algorithms.

The BCM2044 is intended for basic audio headsets that don't require extensive feature programmability. The ROM-based, single-chip device has the same low-power radio and audio architecture as the BCM2047 and also integrates a power management unit including "comprehensive" safety circuitry.

The BCM2047 and BCM2044 are both paired with a "specially tuned version" of Broadcom's BTE Bluetooth software that is optimized for audio applications.

Both devices are currently sampling to "early access" customers, with development kits and reference designs available. Pricing was not given.
