Chapter 2 – SocketModem (MT5600SMI
& MT5656SMI)
Introduction
The Multi-Tech SocketModem creates communication-ready devices by integrating data/fax/voice functionality into a single
product design. The SocketModem is a space-efficient (1" × 2.5"), embedded modem that provides V.92 or V.34/33.6K data
communication. The complete, ready-to-integrate modem dramatically reduces development time and costs for system
designers.
The MT5600SMI/MT5656SMI SocketModem is a standard 64-pin modem used for integrating data communications.
• It is a single-port modem that integrates the controller, DSP, and DAA in a 1" x 2.5" form factor and communicates to a
host controller via an asynchronous serial interface.
• It is available with an 8-bit parallel interface.
