Description  
ST-BUS or variable-rate SSI PCM interfaces  
The MT9122 Voice Echo Canceller implements a  
cost effective solution for telephony voice-band echo  
cancellation  
requirements. The MT9122 architecture contains two  
echo cancellers which can be configured to provide  
dual channel 64 millisecond echo cancellation or  
single channel 128 millisecond echo cancellation.  
The MT9122 supports ITU-T G.165 or G.164 tone  
disable requirements.
