256 Channel Voice Echo Canceller

The ZL50211 Voice Echo Canceller implements a cost effective solution for Telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The ZL50211 architecture contains 128 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 256 channels of 64 milliseconds to 128 channels of 128 milliseconds echo cancellation or any combination of the two configurations. The ZL50211 supports ITU-T G.165 and G.164 Tone disable requirements.
