Overview

CS470xx CS470xx Data Sheet Features The CS470xx family is a new generation of audio system-on-a-chip (ASOC) processors targeted at high  Cost-effective, High-performance 32-bit DSP fidelity, cost sensitive designs.
Derived from the highly  300,000,000 MAC/S (multiply accumulates per second) successful CS48500 32-bit fixed-point audio enhancement processor family, the CS470xx further simplifies system  Dual MAC cycles per clock design and reduces total system cost by integrating the S/  72-bit accumulators are the highest precision in the industry  32K x 32-bit SRAM with three 2K blocks assignable to either Y data or program memory 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  Integrated DAC and ADC Functionality smaller, less expensive board designs.
 8† Channels of 24-bit DAC output: 108dB DR, –98 dB THD+N  4† Channels of 24-bit ADC input: 105dB DR, –98 dB THD+N Target applications include:  Automotive head units and outboard amplifiers  Automotive processors and automotive integration hubs  Integrated 5:1 analog mux feeds one stereo ADC  Digital TV  Configurable Serial Audio Inputs and Outputs  MP3 docking stations  Integrated 192 kHz S/PDIF Rx  Integrated 192 kHz S/PDIF Tx  Supports 32-bit serial data @ 192 kHz  Supports 32-bit audio sample I/O between DSP chips  TDM I/O modes  Supports Different Sample Rates (Fs)  Three integrated hardware SRC blocks  Output can be master or slave  Supports dual-domain Fs on S/PDIF vs.
I²S inputs  DSP Tool Set with Private Keys Protect Customer IP  Integrated Clock Manager/PLL  Flexibility to operate from internal PLL, external crystal, external oscillator  Input Fs Auto Detection w/ µC Acknowledgement  AVR and DVD RX  DSP controlled speakers (subwoofer...
