Ordering Information:

See

The CS470xx family is a new generation of audio system-on-

a-chip (ASOC) processors targeted at high fidelity, cost

sensitive designs. Derived from the highly successful

CS48500 32-bit fixed point audio enhancement processor

family, the CS470xx further simplifies system design and

reduces total system cost by integrating the S/PDIF Rx,

S/PDIF Tx, analog inputs, analog outputs, and SRCs. For

example, a hardware SRC can down-sample a 192 kHz

S/PDIF stream to a lower Fs to reduce memory and MIPS

requirements for processing. This integration effectively

reduces the chip count from 3 to 1 which allows smaller, less

expensive board designs.

Target applications are:

The CS470xx is programmed using the simple yet powerful

Cirrus proprietary DSP Composer

pre-production tuning tool. Processing chains may be

designed using a drag-and-drop interface to place/utilize

functional macro audio DSP primitives and custom audio

filtering blocks. The end result is a software image that is

downloaded to the DSP via serial control port.

The Cirrus Framework

Assembly and C language compilers and other software

development tools for porting existing code to the CS470xx

family platform.
