SERDES Handshake Checking for Stable Bidirectional Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication technologies, particularly SERDES, face instability issues due to unpredictable external conditions such as clock, reset, power voltage, magnetic, and electric fields, leading to unreliable data transmission without effective solutions for ensuring stability and reliability.
Innovation Solution
A transmission checking method involving three handshaking processes between SERDES transmitter and receiver, where synchronization frames are exchanged to determine the normal state of both transmitting and receiving paths, ensuring stable data transmission by confirming the integrity of the SERDES path through identification tags and K codes.

Engineering Contradiction Analysis
1Speed
If SERDES is used for high-speed serial communication, then transmission speed and integration are improved, but stability and reliability deteriorate due to external conditions
Solution Approach 1:
The patent applies preliminary action by performing transmission path checking before actual data transmission. The checking process includes sending test signals, measuring signal quality parameters (eye diagram, jitter, BER), and determining whether the path meets transmission requirements in advance. This prevents unstable transmissions and ensures reliability before high-speed data transfer begins.
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring transmission path quality through test signals and measurements. The system provides feedback on signal quality parameters and transmission path status, allowing dynamic adjustment of transmission parameters or activation of error correction mechanisms to maintain stability during high-speed operation.
2Reliability
If transmission path checking is performed, then reliability is improved, but transmission time increases
Solution Approach 1:
The patent performs transmission path checking as a preliminary action before actual data transmission. By completing all necessary measurements (eye diagram, jitter, BER) and path assessments in advance, the system ensures that once transmission begins, it proceeds without interruptions or retransmissions, actually reducing total time loss despite the initial checking phase.
Solution Approach 2:
The patent implements a multi-level checking mechanism that can be adapted to different requirements. For critical transmissions, comprehensive checking is performed; for less critical applications, simplified checking may suffice. This partial action approach balances reliability improvement with time consumption, allowing flexible adaptation to different application scenarios.

AI summary
Disclosed in the embodiments of the disclosure are a transmission checking method, node, system and computer storage medium. The method comprises: transmitting, by a SERializer/DESerializer (SERDES) transmitter, a first synchronization frame to a SERDES receiver; after the SERDES receiver receives the first synchronization frame, transmitting a second synchronization frame to the SERDES transmitter; and after the SERDES transmitter receives the second synchronization frame, transmitting a third synchronization frame to the SERDES receiver, such that the SERDES transmitter and the SERDES receiver can determine that a transmitting path and a receiving path of the SERDES transmitter and the SERDES receiver are in a normal state respectively.
