MT93L04AG [Microchip]

The MT93L04 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The MT93L04 architecture contains 64 groups of two echo cancellers (ECA and ECB) which can be configured to provide two channels of 64 milliseconds or one channel of 128 milliseconds echo cancellation. This provides 128 channels of 64 milliseconds to 64 channels of 128 milliseconds echo cancellation or any combination of the two configurations. The MT93L04 supports ITU-T G.165 and G.164 tone disable requirements.
