IS1682S数据手册Microchip中文资料规格书

描述 Description

The IS1682S is a highly integrated ultra-low power, single-chip RF and baseband IC for Bluetooth v3.0+EDR Single/Dual-MIC applications. The IS1682S builds in an audio processor and high performance stereo codec to support the enhanced audio and speech. To provide superior audio and voice quality, it also integrates a DSP co-processor, a PLL, and a stereo CODEC to process voice and audio applications. For voice, not only basic A-law/μ-law/CVSD encoding/decoding but also enhanced noise reduction and echo cancellation are implemented by the built-in DSP to reach better quality in the both sending and receiving sides. In addition, a power management unit and program ROM/RAM are integrated to reduce BOM cost for various Bluetooth applications.
