A system and method utilizing at least three transmitters, where only two are conductive and one is in a high-impedance state, allowing for data transmission over multiple lines with reduced power consumption and lower parasitic capacitance, while also employing common mode termination to minimize signal noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transmitters are activated for data transmission, then data transmission capability is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between different transmitter configurations (1 transmitter active, 2 transmitters active, or 3 transmitters active) based on data transmission requirements. This dynamic adaptation allows the system to optimize power consumption while maintaining the necessary data transmission capability, resolving the contradiction between productivity and energy use.
Solution Approach 2:
The invention changes the operational parameters of the transmitters by introducing multiple conductive states (single transmitter conductive, two transmitters conductive, or three transmitters conductive). This parameter variation enables the system to adjust power consumption levels while maintaining data transmission functionality, effectively resolving the technical contradiction.
2Speed
If multiple transmitters are activated for data transmission, then data transmission rate is improved, but signal noise increases
Solution Approach 1:
The system dynamically adjusts the number of active transmitters based on signal quality requirements. By switching between different transmitter activation states, the system can achieve high data transmission rates when signal conditions permit, while reducing signal noise by activating fewer transmitters when necessary, thus resolving the contradiction between speed and harmful factors.
3Reliability
If all transmitters are conductive, then data transmission redundancy is improved, but parasitic capacitance increases
Solution Approach 1:
The invention introduces multiple conductive state parameters (one transmitter conductive, two transmitters conductive, or three transmitters conductive) to control the level of redundancy. This parameter-based approach allows the system to achieve the desired reliability through selective redundancy while minimizing parasitic capacitance by not keeping all transmitters conductive simultaneously, thus resolving the technical contradiction.
