www.DataSheet4U.com MT93L04 128-Channel Voice Echo Canceller Data Sheet 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 Ordering Information MT93L04AG 365 Ball BGA Trays MT93L04AG2 365 Ball BGA** Trays **Pb Free Tin/Silver/Copper -40° C to +85 ° C Echo Canceller pools DCME, satellite and multiplexer systems January 2006 Description The MT93L04 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The MT93L04 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 MT93L04 supports ITU-T G.165 and G.164 tone disable requirements. Applications Voice over IP network gateways Voice over ATM, Frame Relay T1/E1/J1 multichanne...
