Features

Description The CS6403 is an application-specific digital signal processor optimized for network and acoustic echo cancellation applications. A high-quality codec is integrated with the processor to provide a complete, lowcost echo-cancellation solution. The CS6403 is a fully independent processor that requires no signal processing support to implement its cancellation functions. Volume control, AGC, and sleep functions are also provided. The on-chip ADC and DAC employ over-sampling technology, which eliminates the need for complex external anti-aliasing and reconstruction filters, further red.
