CS49DV8C Data Sheet
32-bit Audio DSP Family
1. Documentation Strategy
The CS49DV8C data sheet describes the CS49DV8C family of multichannel audio DSPs. This
document should be used in conjunction with the following documents when evaluating or designing a
system around the CS49DV8C family of processors.
The scope of the CS49DV8C Data Sheet is primarily the hardware specifications of the CS49DV8C
devices. This includes hardware functionality, characteristic data, pinout, and packaging information.
The intended audience for the CS49DV8C Data Sheet is the system PCB designer, MCU programmer,
and the quality control engineer.
2. Overview
The CS49DV8C DSP is designed to provide high-performance volume control using the Dolby Volume
algorithm. The CS49DV8, supports up to 7.1 Channels of Dolby Volume processing at 48 kHz, 44.1 kHz
or 32 kHz while leaving the 2nd core of the DSP completely available for even further processing
functions such as Quadruple Crossover Bass Management, Tone Control, and Multiband Parametric
EQ.
The CS49DV8C DSP, together with Cirrus Logic’s comprehensive library of audio processing algorithms,
enables the development of next-generation high-definition audio solutions. Cirrus Logic also provides a
broad array of digital interface products, and audio converters, to meet your audio system-level design
requirements.
The CS49DV8C is available in a 128-pin LQFP package.
Please refer to Table 2 on page 6 for the processor speed and available firmware for the CS49DV8C
product family.
