Description
The ZL50233 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation
conforming to ITU-T G.168 requirements. The ZL50233 architecture contains 2 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 4 channels of 64 milliseconds to 2 channels of 128 milliseconds echo cancellation
or any combination of the two configurations. The ZL50233 supports ITU-T G.165 and G.164 tone disable
requirements.
