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
