CSR8675
Programmable
Bluetooth dual-mode
System on Chip (SoC)
CSR8675 is a premium tier single-chip
solution in our CSR86xx Bluetooth audio
SoC portfolio delivering high quality
wireless audio performance and supporting
development of highly differentiated
premium wireless audio products.
CSR8675 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.
The CSR8675 SoC also integrates a dedicated active
noise-cancelling** block for earbud and headphone
applications, and a 120Mhz Qualcomm® Kalimba™
DSP, which allows support for 24-bit audio over
Bluetooth and aptX HD* making it an ideal choice for
premium audio products.
The Audio Development Kit (ADK)* software for
CSR8675 includes Bluetooth applications, voice and
music technologies and tuning tools for reference
headset and speaker applications and supports
developers with greater dierentiation capabilities in a
single-chip design.
Qualcomm BlueCore, Qualcomm aptX, CSR8675, and Qualcomm Kalimba are products of Qualcomm Technologies International, Ltd.
* Requires ADK software and separate licenses.
** Available in 2017 via separate software download. Requires ADK software and
separate licenses. (Subject to change)
