BCM2049数据手册Broadcom中文资料规格书

描述 Description

Cost-effective solution for portable devices like mobile handsets and media players that require Bluetooth, an FM receiver/transmitter and advanced music functionality. At the software layer, the BCM2049 builds upon Broadcom's BCM2048 Bluetooth + FM receiver API, making it fully backward compatible. The BCM2049's Bluetooth core is optimized for low current consumption and a minimal external bill-of-materials costs, while maintaining high receiver sensitivity and up to +10 dBm of transmit output power. The Bluetooth core is fully Bluetooth 2.1 + EDR compliant. SmartAudio® technology has also been added to enhance voice quality by supporting packet loss concealment and wide-band speech. In conjunction with Broadcom's BTE-Mobile software stack, the BCM2049 supports multiple simultaneous Advanced Audio Distribution Profile (A2DP) streams, enabling music sharing between several stereo Bluetooth headsets.
