Chapter 9 – SocketModem® (MT9234SMI)
Introduction
Multi-Tech’s 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.92/56K communication.
The complete, ready-to-integrate modem dramatically reduces development time and costs for system designers.
The MT9234SMI SocketModems are used for integrating data and fax communications. They are single-port modems that
integrate the controller, DSP, and DAA in a 1" x 2.5" form factor and communicate to a host controller via an asynchronous
serial interface.
