ELECTRICAL ANALYSIS REPORT Use OF Z-PACK 2mm HM for Fibre Cannel Applications
●Executive Summary
■The Fibre Chaimel Working Group is currently considering switching the system impedance of the Fibre Channel Specification from 150Ω differential to 100Ω differential. Due to legacy issues, it is anticipated that mixed impedance systems will be developed. AMP examined the performance of the 2mm Z-PACK HM connector in various environments based on device parameters intended for 2.125 Gb/s operation.
■For the Z-PACK HM connector, the variation in single-ended noise between a system based entirely on 15〇Q and a mixed impedance configuration was 15 mV. The variation in differential noise between a complete system based on 15〇Q or a mixed impedance configuration was 5 mV. Thus, the difference in performance was less than 1%. This type of performance indicates that the 2mm Z-PACK HM coimector with the pinout AMP proposed could be an excellent candidate for a Fibre Channel system operating at 2.125 Gb/s, regardless of the impedance configuration of the system.
■The system's capability to perform will depend on the overall architecture that the engineer develops and the manner in which it is implemented. AMP Incorporated strongly recommends that gigabit applications always be simulated. For mixed impedance Fibre Chaimel Systems, simulation could make the difference between a functional and non-flmctional design.
