CS470xx Overview
The CS470xx family is a new generation of audio system-on-a chip (ASOC) processors targeted at high fidelity, cost sensitive designs. Starting with the single-core 32-bit audio DSP engine, the CS470xx family further simplifies system design and reduces total system cost by integrating the S/PDIF Rx, 2 S/PDIF Tx, dual stereo analog inputs – one with 5:1 stereo input mux, up to 8 analog outputs, and up to 20 channels of hardware SRCs to simplify system design. This integration effectively reduces an equivalent system chip count (using the CS47048 device) from 16 to 1 which clearly allows for much smaller, less expensive board designs.
