Data Detection on Serial Communication Links - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240283436 titled 'Data Detection on Serial Communication Links
The abstract describes a patent application for a serial data receiver subsystem in a computer system. The subsystem includes a data rate detection circuit and a receiver circuit. The data rate detection circuit detects whether a communication link operates in high-speed mode by analyzing the number of transitions in a serial data stream over a reference period. If the number of transitions exceeds a threshold value, a data rate detection signal is activated. The receiver circuit then activates specific subcircuits in response to the data rate detection signal.
- The data rate detection circuit determines if a communication link is operating in high-speed mode by counting transitions in a serial data stream.
- If the number of transitions exceeds a threshold value, a data rate detection signal is triggered.
- The receiver circuit responds to the data rate detection signal by activating specific subcircuits within the receiver circuit.
Potential Applications: - This technology can be used in high-speed data communication systems to optimize data reception. - It can enhance the performance of serial data receivers in various electronic devices.
Problems Solved: - Efficiently detecting the data rate of a communication link. - Improving the responsiveness of receiver circuits based on the detected data rate.
Benefits: - Enhanced data reception capabilities. - Improved overall performance of communication systems. - Optimal utilization of high-speed communication links.
Commercial Applications: Title: "Enhanced Serial Data Receiver Subsystem for High-Speed Communication Systems" This technology can be applied in telecommunications equipment, networking devices, and data storage systems to improve data transmission efficiency and reliability. It can also benefit industries that rely on high-speed data communication for their operations.
Questions about Serial Data Receiver Subsystem: 1. How does the data rate detection circuit differentiate between high-speed and low-speed modes? The data rate detection circuit analyzes the number of transitions in a serial data stream over a reference period to determine the operating mode.
2. What are the advantages of activating specific subcircuits in response to the data rate detection signal? Activating specific subcircuits allows the receiver circuit to adapt to the detected data rate, optimizing data reception and overall system performance.
Original Abstract Submitted
a serial data receiver subsystem of a computer system includes a data rate detection circuit and a receiver circuit. the data rate detection circuit is configured to detect that a communication link operates in a high-speed mode rather than in a low-speed mode by detecting that a number of transitions in a serial data stream over a reference period of time exceeds a threshold value. the date rate detection circuit is further configured to activate a data rate detection signal indicating that the communication link operates in the high-speed mode, the data rate detection signal activated in response to detection that the number of transitions in the serial data stream over the reference period of time exceeds the threshold value. the receiver circuit is configured to activate one or more of a plurality of subcircuits included in the receiver circuit in response to activation of the data rate detection signal.
