CS6403
Echo-Cancelling Codec
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 reducing system cost. The CS6403 has a serial interface that is compatible with most DSPs and PCM codecs. Clock and sync lines control the transfer of serial data via the separate serial datain and data-out pins. Both 16-bit audio data and control/status information may be multiplexed on this serial channel using a steering bit. ORDERING INF.
