Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional clock design and configuration methods are used, then data processing capability and flexibility are maintained, but system complexity increases and clock configuration becomes increasingly difficult
Solution Approach 1:
The patent implements a universal clock management unit that can configure multiple transmit and receive channels with different line rates and data bit widths using a single reference clock. The clock management unit determines frequency division coefficients based on channel requirements and automatically generates appropriate operating clock frequencies, making the clock system adaptable to various communication protocols and rates without requiring separate clock circuits for each channel.
Solution Approach 2:
The patent changes the parameters of the reference clock by dynamically adjusting the frequency division coefficient based on the required line rate and data bit width. Instead of using multiple fixed-frequency clocks, the system modifies the division ratio parameter to generate different operating frequencies from a single reference clock, thereby reducing system complexity while maintaining adaptability.
2Adaptability or versatility
If independent line rates and sampling frequencies are used for each channel, then data transmission flexibility is improved, but the number of clocks required increases
Solution Approach 1:
The patent merges multiple independent clock sources into a single reference clock that serves all transmit and receive channels. The clock management unit combines the function of generating and configuring clocks for multiple channels into one unified unit, which determines frequency division coefficients and distributes the appropriate operating frequencies to each channel as needed.
Solution Approach 2:
The reference clock is designed to perform multiple functions by serving as the clock source for all channels simultaneously. Through the clock management unit, a single reference clock can be divided into different frequencies to support multiple transmit and receive channels with different data rates, eliminating the need for separate clocks for each channel.
3Productivity
If more data transmission channels are integrated into each communication module, then data processing capability is improved, but clock configuration difficulty increases
Solution Approach 1:
The clock management unit implements self-service by automatically determining the frequency division coefficients based on the required line rates and data bit widths of each channel. The system configures itself without external intervention, calculating the appropriate operating clock frequencies and distributing them to the respective channels, thereby simplifying clock configuration even as the number of channels increases.
Solution Approach 2:
The system handles multiple channels by dynamically changing the frequency division coefficient parameter for each channel based on its specific requirements. The clock management unit adjusts the division ratio parameter automatically, allowing the same reference clock to serve multiple channels with different data rates without manual configuration complexity.
