The CS47048 family is a new generation of audio system-on-achip (ASOC) processors targeted at high fidelity, cost sensitive designs. Derived from the highly successful CS48500 32-bit fixed point audio enhancement processor family, the CS47048 further simplifies system design and reduces total system cost by integrating the S/PDIF Rx, S/PDIF Tx, analog inputs, analog outputs, and SRCs to simplify system design. For example, a hardware SRC can down-sample a 192kHz 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:
