Integrated Bluetooth® audio ROM platform with Qualcomm® aptX™ audio and Qualcomm® cVc™ noise cancellation technology.
The CSR8645 dual-mode ROM audio SoC is designed to offer extensive voice and music capabilities in a ROM-based package, including aptX and cVc, making it ideal for a variety of wireless audio products with support for voice and music. The CSR8645 is part of the CSR86xx portfolio, a range of silicon platforms for wireless audio applications which integrate a dual-mode Bluetooth radio, a low power DSP, an application processor, a battery charger, memory and various audio and hardware interfaces into a single-chip solution. Developed for entry-level to mid-range wireless audio devices, the CSR8645 SoC supports cVc voice processing technology and aptX codec technology to deliver high quality voice and music capabilities in a costefficient ROM-based single-chip package. The CSR8645 is an easy and cost-effective platform for developing wireless audio products and supports reduced development time. It is an ideal solution for a range of highly differentiated home entertainment and wearable audio products including stereo headphones, speakers, speakerphones, headsets and hands-free devices.
CSR8645, Qualcomm aptX, Qualcomm cVc and Qualcomm Kalimba are products of Qualcomm Technologies, Inc., and/or its subsidiaries.
aptX audio technology supports high-quality wireless audio, bringing pro-audio quality to consumer electronic devices.
Application processor, Bluetooth and Bluetooth low energy radios, DSP and memory integrated into a single SoC helps reduce system complexity and eBOM while supporting small form factor designs.
Pre-loaded Bluetooth and audio applications allow manufacturers to develop end-products without writing code, while customization tools support quick modification of device behaviour and user interface.
cVc technology is a suite of algorithms designed to work on the transmit and receive path of voice calls to deliver optimum voice quality on Bluetooth headsets, handsets, hands-free devices, and automotive.
