Data Detection on Serial Communication Links - A simplified explanation of the abstract
This abstract first appeared for US patent application 17823952 titled 'Data Detection on Serial Communication Links
Simplified Explanation
- The patent application describes a serial data receiver subsystem for a computer system. - The subsystem includes a data detection circuit, a speed detection circuit, and a receiver circuit with multiple subcircuits. - The data detection circuit compares received signals to a reference voltage to determine the presence of data on a communication link. - The speed detection circuit counts the number of transitions to determine the rate of data transmission. - If the rate exceeds a threshold value, the receiver circuit activates one or more subcircuits. - The innovation allows for efficient and accurate detection and processing of serial data streams in a computer system.
Original Abstract Submitted
A serial data receiver subsystem included in a computer system may include a data detection circuit, a speed detection circuit, and a receiver circuit that includes multiple subcircuits. The data detection circuit performs a comparison a reference voltage to the magnitude of signals received via a communication link that encode a serial data stream consisting of multiple data symbols. Using a result of the comparison, the data detection circuit may activate a indicating the presence of data on the communication link. Once the is active, the speed detection circuit checks the number of transitions to determine a rate at which data is being transmitted. In response to a determination that the rate of the data being transmitted exceeds a threshold value, the receiver circuit activates one or more of the multiple subcircuits.
