MT9123AP1 [Microchip]

The MT9123 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.165 requirements. The MT9123 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 MT9123 operates in two major modes: Controller or Controllerless. Controller mode allows access to an array of features for customizing the MT9123 operation. Controllerless mode is for applications where default register settings are sufficient.
