ZL50232 General Description
The ZL50232 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation Aconforming to ITU-T G.168 requirements. The ZL50232 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 ZL50232 supports ITU-T G.165 and G.164 tone disable requirements
