  • Page 11: System Description

    2 SYSTEM DESCRIPTION 2.1 MAFE INTERFACE The Modem Analog Front End (MAFE) Interface is a serial port integrated into the TERIDIAN TERIDIAN73M1903 device to interface to a host processor or a DSP. This serial data port is a bi- directional port that can be supported by most DSPs with a synchronous serial port or GPIO that can be configured as a serial port.

    73M1903 MODEM ANALOG FRONT END DEMO BOARD User’s Manual 2.3 73M1903 SYSTEM INITIALIZATION The following example shows the sequence to bring the 73M1903 device out of reset and to start up after power up. NOTE: The TERIDIAN73M1903 device does not have an automatic power on reset circuit. After the power has stabilized, a reset signal should be asserted from the host by pulling the reset pin low for 100ns or longer.

  • Page 17: Hardware Description

    3 HARDWARE DESCRIPTION 3.1 BOARD SETTING: JUMPERS AND CONNECTORS Figure 3-1 shows the connectors and jumpers available on 73M1903 Demo Boards. JS1 is the main connector for communicating with a host processor or DSP board. The pins of this interface connector are configurable by 0 Ohm resistors.

  • Page 18: Table 3-1: 73M1903 Demo Board Connectors

    Ring detector Three-pin header that allows selection of the Ring detector output output to connect to either GPIO4 of 73M1903 or to a Host CPU GPIO through JS1 or JP25. 1-2: Ring detector output is fed to 73M1903 GPIO4. (73M1903 GPIO4 must be configured as an input.)

  • Page 19: Table 3-3: 73M1903 Demo Board Jumper Settings

    JS1 can be to be used in applications where the 73M1903 demo board is plugged directly into a target application or adaptor board. It also allows flexibility in the assignment of the signals to the connector. If a ribbon cable connection is preferred, JP2 can be used instead.
