Description

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 supportsITU-T G.165 or G.164 tone disable requirements.

Features

? Dual channel 64ms or single channel 128ms echo cancellation

? Conforms to ITU-T G.165 requirements

? ITU-T G.165/G.164 disable tone detection supported on all audio paths

? Narrow-band signal detection

? Programmable double-talk detection threshold

? Non-linear processor with adaptive suppression threshold and comfort noise insertion

? Offset nulling of all PCM channels

? Controllerless mode or Controller mode with serial interface

? ST-BUS or variable-rate SSI PCM interfaces

? Selectableμ/A-Law ITU-T G.711; μ/A-Law Sign Mag; linear 2’s complement

? Per channel selectable 12 dB attenuator

? Transparent data transfer and mute option

? 19.2 MHz master clock operation

Applications

? Wireless Telephony

? Trunk echo cancellers
