Bluetooth reference design by Broadcom for designing handsfree car kits

Broadcom has made available a new Bluetooth reference design platform for hands-free car kit devices. This new design platform based on Broadcom's BCM20741 family of Bluetooth system-on-a-chip (SoC) devices for headset devices includes an upgrade to its SmartAudio sound and voice enhancement technology to reduce background noise. Samsung has adopted this new platform for its HF1000 car kit device.

Due to implementation of 'hands-free' laws in some parts of the world such as China where use of car kits and headsets are must when talking on a cell phone while driving, hand-free kits are gaining importance.

This upgraded version provides all the components required to manufacture car kit devices.

Key features that this Reference design include:

Echo cancellation that improves 'double-talk' performance.
'Near-end' speech intelligibility
Integrated multiple language voice prompts (in on-chip ROM).
An integrated power management unit to recharge car kit batteries
Tunable audio algorithms to adapt to various form factors.
Differentiates between voice and non-voice characteristics while eliminating background noise to deliver a clear conversation.

Craig Ochikubo, Vice President & General Manager, Broadcom's Wireless Personal Area Networking line of business said "We continue to grow in the Bluetooth hands-free market by delivering a superior audio experience that provides key user benefits, and is friendly to the end-user and the environment. New car kit products based on our technology also benefit from the latest version of our popular SmartAudio technology with revolutionary noise suppression technologies optimized particularly for car kits."
