MTC20136MB-I1 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
   The MTC20136 is a dedicated controller chip, specifically designed to control operations of the STMicroelectronics DynaMiTe chipset. The MTC20136 offers direct glueless interfaces to the MTC20135 and MTC20455 DMT/ATM transciever and implements a complete control interface for parameters and commands exchange between transceiver and system management. All real time ADSL-related functions (including EOC processing) are completely handled by the MTC20136.

■ Dedicated controller for use with ADSL
   transceiver chips MTC20134, MTC20135 and
   MTC20455
