Dual Voice Echo Canceller (ITU-T G165 Compliant) With Disable Tone Detection

The MT9122 Voice Echo Canceller implements a cost effective solution for Telephony voice-band echo cancellation conforming to ITU-T G.165 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. The MT9122 operates in two major modes: Controller or Controllerless. Controller mode allows access to an array of features for customizing the MT9122 operation. Controllerless mode is for applications where default Register settings are sufficient.
