5 / 26 page CS485xx Family Data Sheet 32-bit Audio Decoder DSP Family DS734F3 Copyright 2009 Cirrus Logic, Inc. 5 CONFIDENTIAL 1. Documentation Strategy The CS485xx Family Data Sheet describes the CS485xx family of multichannel audio processors. This document should be used in conjunction with the following documents when evaluating or designing a system around the CS485xx family of processors. 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. Please refer to Table 2 on page 7 for the input, output, firmware features of each device. 2.1 Licensing Licenses are required for all of the 3rd party audio processing algorithms listed in Section 3. Please contact your local Cirrus Logic Sales representative for more information. Table 1.
