EVALUATION METHOD FOR DIGITAL DATA LINK, EVALUATION CIRCUIT FOR DATA TIMING JITTER AND COMBINATION METHOD FOR SIMULTANEOUSLY EXECUTING SELECTION OF RETIMING SIGNAL AND EVALUATION OF DIGITAL DATA LINK

摘要

PURPOSE: To evaluate digital data link performance by measuring the quality of data received through a link. ;CONSTITUTION: The number of data edges sorted for n-pieces of time intervals defining edge histogram is compared with a prescribed threshold level. A monitor signal is generated by respective comparisons. The combination of the monitor signals is analyzed and the quality of the link is decided after the quantity of data timing jitter is decided.;COPYRIGHT: (C)1993,JPO
