Chapter 3 – SocketModem
(MT5634SMI & 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 MT5634SMI and 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
Notes:
• The MT9234SMI is a newer modem that will, in the near future, be replacing the MT5634SMI. The functionality
of this MT9234SMI will be the same as the MT5634SMI.
• MT9234SMI is recommended for new designs.
