Description
This document
Includes detailed system design information including Typical Connection Diagrams,
Boot-Procedures, Pin Descriptions, etc.
Includes detailed firmware design information including signal processing flow
diagrams and control API information
Includes detailed configuration and usage information for the GUI development tool.
The scope of the CS485xx Family Data Sheet is primarily the hardware specifications of the CS485xx family of devices.
This includes hardware functionality, characteristic data, pinout, and packaging information.
The intended audience for the CS485xx Family Data Sheet is the system PCB designer, MCU programmer, and the quality
control engineer.
2 Overview
The CS485xx DSP Family is designed to provide high-performance post-processing and mixing of digital audio. The dual
clock domain provided on the PCM inputs allows for the mixing of audio streams with different sampling frequencies. The
low-power standby preserves battery life for applications which are always on, but not necessarily processing audio, such
as automotive audio systems.
There are three devices comprising the CS485xx family. The CS48520, CS48540 and CS48560 are differentiated by the
number of inputs and outputs available. All DSPs support dual input clock domains and dual audio processing paths. All
DSPs are available in a 48-pin QFP package. Refer to Table 3-1 for the input, output, firmware features of each device.
