GENERAL DESCRIPTION
ISSC To provide the best audio and voice quality, it also integrates a DSP co-processor, and a high performance stereo CODEC to handle 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 audio processor to reach the best quality in the both sending and receiving sides. For enhanced audio applications, SBC or MP3 encoding/decoding functions are also carried out by audio processor to satisfy A2DP requirements. In addition, to minimize the external components required for portable devices, a voltage sensor for battery, battery charger, a switching regulator and LDOs are integrated to reduce BOM cost for various Bluetooth applications. The device incorporates built-in self-test (BIST) and auto-calibration functions to simplify production test. 2.FEATURES
