ZL38065 General 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 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 ZL38065 supports ITU-T G.165 and G.164 tone disable requirements.

ZL38070 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 50 ms initial convergence times under many typical network conditions
• Unparalleled in-system tunability
• The ZL38070 provides more than 58% board space savings when compared with eight individually packaged Echo Voice Processor devices
