Integrated Chip Strobe Switching for Initial Data-Eye Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As data transmission frequency increases, the initial data-eye for recognizing data becomes smaller due to noise, leading to potential recognition errors in integrated circuit chip communications.
Innovation Solution
The integrated circuit chip employs a strobe signal supply unit that generates a second clock signal at a lower frequency during the initial period of data packet transmission and switches to a first clock signal at a higher frequency after the initial period, ensuring proper data recognition and transmission.

Engineering Contradiction Analysis
1Productivity
If data transmission frequency is increased to achieve higher data transmission rate, then productivity is improved, but measurement precision deteriorates due to reduced data-eye size
Solution Approach 1:
The strobe signal frequency is dynamically adjusted based on the transmission stage: a first frequency is used during the initial period when data-eye is small, and a second frequency is used after the initial period when data-eye is larger. This dynamic frequency adjustment allows the system to achieve high data transmission rates overall while maintaining data recognition accuracy during the critical initial stage.
Solution Approach 2:
The patent changes the frequency parameter of the strobe signal according to different transmission phases. By switching between two frequency values (first frequency during initial period, second frequency after initial period), the system optimizes both data recognition precision and transmission rate at different stages of data packet transmission.
2Productivity
If data transmission frequency is increased, then data transmission rate is improved, but reliability deteriorates due to data recognition errors in initial data
Solution Approach 1:
The strobe signal frequency is dynamically adjusted based on the transmission stage: a first frequency is used during the initial period when data-eye is small, and a second frequency is used after the initial period when data-eye is larger. This dynamic frequency adjustment allows the system to achieve high data transmission rates overall while maintaining data recognition accuracy during the critical initial stage.
Solution Approach 2:
The patent applies a different strobe signal frequency in advance during the initial period of data transmission, before the main data transmission phase. This preliminary action with a first frequency ensures that initial data packets are transmitted reliably, preventing recognition errors that would compromise overall transmission reliability.
3Productivity
If a single high frequency strobe signal is used throughout transmission, then productivity is improved, but measurement precision deteriorates during the initial period
Solution Approach 1:
The data transmission process is segmented into two distinct periods: an initial period and a subsequent period. Different strobe signal frequencies are applied to each segment - a first frequency during the initial period for accurate recognition, and a second frequency afterward for high-speed transmission. This segmentation resolves the contradiction by allowing each phase to operate at its optimal frequency.
Solution Approach 2:
The patent applies different quality characteristics (frequencies) of the strobe signal to different parts of the transmission process. The initial period receives a first frequency optimized for data recognition precision, while the subsequent period receives a second frequency optimized for transmission rate. This local quality differentiation ensures both precision and productivity are achieved in their respective domains.
