1. Documentation Strategy
The CS48DV2B Data Sheet describes CS48DV2B multichannel audio processors. This document
should be used in conjunction with the following documents when evaluating or designing a system
around the CS48DV2B processors.
The scope of the CS48DV2B Data Sheet is primarily the hardware specifications of the CS48DV2B
devices. This includes hardware functionality, characteristic data, pinout, and packaging information.
The intended audience for the CS48DV2B Data Sheet is the system PCB designer, MCU
programmer, and the quality control engineer.
2. Overview
The CS48DV2B DSP 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.
The CS48DV2B supports dual input clock domains and dual audio processing paths. The
CS48DV2B is 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
