Abstract
A novel structure for reducing cross-talk effect is disclosed. The structure includes an electric board containing a ground layer and a plurality of adapting modules. Only one of the adapting modules can operates at any one time and each adapting module includes a plurality of slots and a plurality of buses. The plurality of the slots can detachably accommodate a plurality of corresponding adapting devices. The buses are electrically connected to the plurality of slots for transmitting signals and data. When the adapting module does not operate, the corresponding the buses are connected to the ground layer of the electric board. The plurality of the buses of the modules are alternately co-laid out on the electric board.
Claims21
A structure for reducing cross-talk comprising:
- an electric board comprising a ground layer;
- and
- a plurality of adapting modules installed on the electric board, wherein only one of the adapting module can operate at a time;
- each adapting module comprising:
- a plurality of slots for detachably accommodating a plurality of corresponding adapting devices;
- and
- a plurality of buses electrically connected to the plurality of slots for transmitting signals and data, wherein when the adapting module does not operate, the corresponding plurality of buses are electrically connected to the ground layer of the electric board;
- wherein the plurality of buses of the plurality of adapting modules are alternately laid out on the electric board.
A method for reducing cross-talk in a different-buses-co-layout structure, the different-buses-co-layout structure comprising a plurality of buses for transmitting different types of signals and data, the method comprising:
- alternately laying out different types of the plurality of buses on an electric board;
- utilizing buses of only one type to transmit signals and data;
- and
- electrically connecting two ends of each bus not transmitting signals and data to a ground layer of the electric board.
A different-buses-co-layout structure for reducing cross-talk comprising:
- an electric board comprising a ground layer;
- and
- two adapting modules installed on the electric board comprising a first adapting module and a second adapting module, wherein the two adapting modules cannot operate at the same time, each adapting module comprising:
- a controller for controlling operations of the adapting modules, the controller comprising a MOS circuit for switching the controller between a predetermined voltage mode and a ground voltage mode wherein when the adapting module does not operate, the MOS circuit switches the controller to the ground voltage mode;
- a plurality of slots for detachably accommodating a plurality of corresponding adapting devices;
- and
- a plurality of buses electrically connected to the plurality of slots for transmitting signals and data, wherein when the adapting module does not operate, the corresponding plurality of buses are electrically connected to the ground layer of the electric board;
- wherein the plurality of buses of the two adapting modules are alternately laid out on the electric board.
