Figure 1 Working principles of the H83DSDMM board

Basic working principles of the H83DSDMM board are as follows:

  • The switch module switches the interface of the backplane to the interface of the chipset module.

  • The chipset module implements functions, such as amplification, filtering, A/D and D/A conversion, coding/decoding, and encapsulation/decapsulation for signals.

  • The protection module protects and isolates the board from lightning strikes.

  • The control module decodes signals and monitors signals.

  • The power module supplies power to other function modules of the board.

  • The clock module provides working clock for other function modules of the board.
