Overview

By integrating the DSP, a microcontroller, power management, LED drivers, analog and digital interfaces and wireless connectivity into a single SoC device, the CSR8670™ and the CSR8675™, the entry-level platform reduces overall system complexity and BoM cost. This offers OEMs and ODMs a fast and simple solution for creating single-chip 2.0 or 2.1 channel soundbar designs. The entry-level design supports analog and digital inputs, audio decoding and post processing, a wireless subwoofer and Bluetooth® audio streaming including support for the aptX® codec from smartphones, tablets, PCs and laptops.

When configured as a 2.1 channel soundbar system, the platform includes a subwoofer design that incorporates a dedicated wireless module based on the CSRA65700™ ROM IC. This works seamlessly with the CSR8670 and CSR8675 in the soundbar to pass the extracted low frequency audio data over the Bluetooth link with a very low relative latency. The subwoofer design enables playback of low frequency audio from an enclosure tuned to deliver an accurate reproduction of bass. As an alternative to the more conventional infra-red remote control, a Bluetooth Smart remote unit can be used for similar functions including volume control and input selection, and additional advanced features like voice command.

CSR's entry-level platform enables a complete wireless solution with all three Bluetooth links operating simultaneously from a central single device, such as as the CSR8670 and the CSR8675
