Todays communication technology requires the transmission of increasingly higher data rates, driving the need for enhanced hardware to preserve signal integrity in these systems. The system designer is challenged to maximize system performance by balancing three interacting components to maximize system performance: ҕ Integrated circuit chips Multi-layer boards Օ Interconnect systemsFCI recognizes that the interconnection of complex subsystems is a crucial factor in the design of data and communications equipment. To meet evolving high-speed performance requirements, we have developed a...

This manual describes the high-speed electrical performanceofthe MEG-Array > and GIG-Array > ή connectors. Throughout thedocument, a number of assumptions and conventions are used. This introduction summarizes the following conventions and assumptions:Definition of reference planes ՕRisetime convention Definition of connector impedance ՕDescription of the mezzanine link The term connector impedance can have different meanings. Itis quite common to grossly simplify the connector and state that it has an impedance of xӔ ohms. This can mean the average impedance of the connector, as measured...

Figure 1-2 shows calibration traces that are equivalent to 2 timesthe length of any trace in the connector measurement area. By shorting the input SMA you are able to locate the beginning of the SMA / Board transition as shown in Figure 1-3. The figure defines this point to be at 5.05ns. If you perform the same procedure on the output SMA you will be able to locate the end of the SMA / Board transition as shown in Figure 1-4. The short on the output islocated at 5.15ns. The measurement details the discontinuity caused by the viatransition where the connector attaches. It is easy to find the...

The mezzanine link used in testing is shown in Figure 1-6. Anumber of channels on the header side are connected to a number of channels on the receptacle side. All connections are point to point, and signals propagate from the header board to the receptacle board. An eye pattern is a good indication of the receivers ability tointerpret signals correctly. It includes the effects of link loss, ISI (intersymbol interference), transmitter jitter, and system noise.To quantify the eye opening, we will use a performance maskbased on the following two performance metrics (Figure 1-7)ҕNormalized...

The propagation delay is the time needed for a signal topropagate through a connector pair. It is calculated as the difference in time between the transmitted signal and input signal at a signal level equal to 50% of the input amplitude. Figures 3-30 thru 3-32 summarize the data for the 4,10 and 14mm stack heights. > Figure 3-31 10mm stack height Delay Figure3-30 4mm stack height Delay Figure3-32 14mm stack height Delay >

Single-pair active crosstalk is the crosstalk measured at onepair when a signal is injected onto a second pair. The backward or near-end crosstalk is the crosstalk measured at the same end as the injected signal. The forward or far-end crosstalk is measured at the end opposite the injected signal. The forward crosstalk is so small in the mezzanine connectors that the values are negligible. Likewise, the single active horizontal and diagonal coupling is also negligible. Therefore, only the near-end multi-pair active crosstalk is presented.Themulti-pair active crosstalk is the maximum...

Figures 3-36 through 3-39 show the reference eye pattern and eyepatterns for MEG-Array > ή at4mm, 10mm and 14mm board-to-boardheights. The impact of trace width, trace length, board material, and vias is included in all of these results. The eye diagrams presented are that of the test configuration outlined in Sections 1.4.1 thru 1.4.3 of this booklet.The input for the differential eye pattern was a 800mVp-p 2 > 7 -1PRBS signal at 10Gb/s. The signal was launched from the header side of the mezzanine link. The mask amplitude was 25% (200 mVp-p) of the input signal and the mask width was set...
