ZL38070 Product details

Description

Data Sheet The ZL38070 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements.The ZL38070 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 c

Features

ZL38070 has eight Echo Voice Processors in a single BGA package. This single device provides 256 channels of 64 msec echo cancellation or 128 channels at 128 msec echo cancellation Each Echo Voice Processor has the capability of cancelling echo over 32 channels Each Echo Voice Processor (EVP) shares the address bus and data bus with each other Fully compliant to ITU-T G.165, G.168 (2000) and (2002) specifications Passed all AT&T voice quality tests for carrier grade echo canceller Sub.
