Description

The MT93L00 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo

cancellation conforming to ITU-T G.168 requirements. The MT93L00 architecture contains 16 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 32 channels of 64 milliseconds to 16 channels of

128 milliseconds echo cancellation or any combination of the two configurations. The MT93L00 supports ITU-T

G.165 and G.164 tone disable requirements.
