Description
   The ZL38065 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The ZL38065 architecture contains 16 groups of two echo cancellers (ECA and ECB) which can be configured to provide two channels of 64 ms or one channel of 128 ms echo cancellation. This provides 32 channels of 64 ms to 16 channels of 128 ms echo cancellation or any combination of the two configurations. The ZL38065 supports ITU-T G.165 and G.164 tone disable requirements.
