Description



Features:

• MT93L04 is a Multi-chip Module (MCM)
  consisting of 4 MT93L00 devices thus providing
  128 channels of 64 msec Echo Cancellation.
• Each device (MT93L00) is independent of the
  each other.
• Each device has the capability of cancelling
  echo over 32 channels.
• The MCM module provides more than 40%
  board space savings.
• Each device (MT93L00) can be programmed
  independently in any mode e.g back to back or
  extended delay to provide capability of
  cancelling different echo tails.
• Each device has the same Jtag identification code.


Application

• Voice over IP network gateways
• Voice over ATM, Frame Relay
• T1/E1/J1 multichannel echo cancellation
• Wireless base stations
• Echo Canceller pools
• DCME, satellite and multiplexer systems

Description

The MT93L04AG Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The MT93L04AG architecture contains 64 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 128 channels of 64 milliseconds to 64 channels of 128 milliseconds echo cancellation or any combination of the two configurations. The MT93L04AG supports ITU-T G.165 and G.164 tone disable requirements.
