Detailed Description

This module is fully compliant with Bluetooth specification and completely backward-compatible with Bluetooth 2.0 or 1.2 systems. It incorporates IS1690S multi-speaker stereo audio chip, 32Kb EEPROM, PCB antenna, and ISSC’s own Bluetooth software stack to achieve the required BT v3.0 with EDR functions. To provide the superior audio and voice quality, it also integrates a DSP co-processor, a PLL, and a CODEC dedicated for voice and audio applications. For voice, not only basic CVSD encoding and decoding but also enhanced noise reduction and echo cancellation are implemented by the built-in DSP to reach the better quality in the both sending and receiving sides. For enhanced audio applications, SBC decoding functions can be also carried out by DSP to satisfy Bluetooth A2DP requirements. In addition, to minimize the external components required for portable devices, a battery voltage sensor , battery charger, a switching regulator and LDO are integrated to reduce system BOM cost for various Bluetooth applications.
