CS470xx Data Sheet
Audio SOC Processor Family
4. Hardware Functional Description
10
The CS470xx family, which includes the CS47048, CS47028, and CS47024 DSPs, is a true
system-on-a-chip that combines a powerful 32-bit DSP engine with analog/digital audio inputs and
analog/digital audio outputs. It can be integrated into a complex multi-DSP processing system, or
stand alone in an audio product that requires analog-in and analog-out. A top level block diagram
for the CS47048, CS47028, and CS47024 products are shown in
respectively.
