The CS470xx Data Sheet describes the CS47048, CS47028, and CS47024 audio processors. This document should be
used in conjunction with the following documents when evaluating or designing a system around the CS470xx processors.
Table 1-1. CS470xx Related Documentation
The scope of the CS470xx Data Sheet is primarily the hardware specifications of the CS470xx family of devices. This
includes hardware functionality, characteristic data, pinout, and packaging information.
The intended audience for the CS470xx Data Sheet is the system PCB designer, MCU programmer, and the quality control
engineer.
2 Overview
The CS470xx DSP is designed to provide high-performance post-processing and mixing of analog and digital audio. Dual
clock domains are supported when the DAI and SPDIF RX inputs are used together. Integrated sample rate converters
(SRCs) allow audio streams with different sample rates to be mixed. The low-power standby preserves battery life for
applications that are always on, but not necessarily processing audio, such as automotive audio systems.
The CS470xx uses voltage-out DACs and is capable of supporting dual input clock domains through the use of the internal
SRCs. The CS470xx is available in a 100-pin LQFP package. Refer to
Table 3-1 and Table 3-2 for the input, output, and
firmware configurations for the CS470xx DSP.
2.1 Licensing
Licenses are required for any third-party audio processing algorithms provided for the CS470xx. Contact your local Cirrus
