【国外标准】 Information Technology - Fibre Channel - Methodologies for Jitter and Signal Quality Specification (FC-MJSQ)

This technical report enhances the jitter and signal specifications found in the Fibre Channel Physical layer standards and in the technical report Methodologies for Jitter Specification (MJS). It provides extended definitions and test methodologies to enable more effective execution of specifications relating to the phase timing features of high speed serial signals. A generalization of jitter concepts to include events that occur at other than the nominal receiver detection threshold provides a stronger coupling between the jitter measured in a signal and the errors produced by the receiver of the signal. The methodologies described use a structured approach to describe the tests that recognize the contributions from test fixtures, instrumentation and calibration schemes to the reported values. Although this report uses 1.0625 GBd for some examples it is intended to be fully applicable to speeds well in excess of the existing 4.25 GBd jitter specifications in FC-PI-n.
