PREFACE Today s communication technology requires the tramission 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: Integrated circuit chips Multi-layer boards Interconnect systems FCI recognizes that the interconnection of complex subsystems is a crucial factor in the design of data and communicatio equipment. To meet evolving high-speed performance requirements, we have developed a compreheive line of two-piece mezzanine connectors. These interconnects provide several levels of performance versus signal deity across a wide range of board-to-board stack heights to eure the proper price and performance objectives are met for a system design. The basic level of performance is provided by the MEG-Array connector system. These connectors are designed for single ended, as well as differential applicatio for stack heights between 4 and 14mm. The GIG-Array connector family offers enhanced performance for differential applicatio where a board-to-board spacing of 15 to 40mm is needed. This manual is designed to assist the designer with the selection of the optimal mezzanine connector solution to meet a defined application need. Section 1 introduces some important terms and concepts used throughout the manual. Section 2 is a summary table comparing the electrical performance for selected stack heights in the two connector families Sectio 3 and 4 present more detailed measured data that characterizes the high-speed electrical performance of the MEG-Array and GIG-Array connector families. Section 5 contai Dimeional Outline Tables Section 6 lists Web Links to additional technical documents for these connector families We hope you will find this guide to be helpful in selecting the proper FCI Mezzanine connectors to meet your application requirements. 4

NOTES 13
INTRODUCTION: ASSUMPTIONS & CONDITIONS This manual describes the high-speed electrical performance of the MEG-Array and GIG-Array connectors. Throughout the document, a number of assumptio and conventio are used. This introduction summarizes the following conventio and assumptio: Definition of reference planes Risetime convention Definition of connector impedance Description of the mezzanine link 1.1 DEFINITION OF REFERENCE PLANES The electrical performance of a pc board is determined by its design (such as board material, trace widths, trace lengths and via hole dimeio) and varies for each application. The measured performance of the board-stacking connectors includes the effects of the test boards and SMA connectors. Figure 1-1 shows the location of the reference planes where measured data was captured. SMA's 1.3 CONNECTOR IMPEDANCE DEFINITION The term connector impedance can have different meanings. It is quite common to grossly simplify the connector and state that it has an impedance of x. This can mean the average impedance of the connector, as measured using a TDR in a specific test configuration, is x. It may also mean that one specific cross-section of the connector has an impedance of x when analyzed with a specific 2-D quasi-static field solver. Without further clarification, the term connector impedance is ambiguous. Even a high-performance mezzanine connector can disrupt the field pattern of propagating energy at high frequencies. The geometry changes associated with via structures and within the connector itself contribute to the field pattern distortion. Typically, the geometric complexity of a multi-pin connector and its attachment to a pc board results in several field pattern distortio, or impedance mismatches that can be represented as lumped elements, either capacitive or inductive. The approach herein is to observe the TDR profile of the entire interconnection link, including all via and board effects. The profile is then characterized for its maximum and minimum impedance deviation at a given risetime. Figures 1-2 thru 1-5 illustrate this approach. Reference Planes Header Receptacle Figure 1-1. Definition of Reference Planes Per this definition all risetimes specified are the risetimes at the input reference plane. 1.2 RISETIME CONVENTION The risetimes shown in this document are at a convention of 10%-90% of signal amplitude. The results obtained with a 100ps 10-90% risetime will always be worse than the results obtained with a 100ps 20-80% risetime. A 10-90% risetime of 100ps corresponds to a 20-80% risetime of 69ps. Similarly, a 20-80% risetime of 100ps corresponds to a 10-90% risetime of 145ps. 14
INTRODUCTION: ASSUMPTIONS & CONDITIONS Figure 1-2 shows calibration traces that are equivalent to 2 times the 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 traition as shown in Figure 1-3. The figure defines this point to be at 5.05. If you perform the same procedure on the output SMA you will be able to locate the end of the SMA / Board traition as shown in Figure 1-4. The short on the output is located at 5.15. INPUT Figure 1-2 Test PCB OUTPUT Figure 1-4 Short at output of calibration SMA The measurement details the discontinuity caused by the via traition where the connector attaches. It is easy to find the discontinuity associated with the via by determining the difference in time between the input and output shorts and then dividing it by two. Using figures 1-3 and 1-4 you can see that the total delay is 100ps and thus the traition to the connector is located at 5.05 + 50ps, or roughly 5.1 as shown in Figure 1-5. Figure 1-5 TDR measurement on empty board Figure 1-3 Short at input of calibration SMA The size of this discontinuity will depend on the impedance of the mated connectors, as well as the impedance of their footprints. The impedance of the footprint depends on board features, such as the layer on which the corresponding signal trace is routed, the size of any via stubs, pad size and antipad size. 15
INTRODUCTION: ASSUMPTIONS & CONDITIONS 1.4 DESCRIPTION OF MEZZANINE LINK 1.4.1 LINK BUILD-UP The mezzanine link used in testing is shown in Figure 1-6. A number of channels on the header side are connected to a number of channels on the receptacle side. All connectio are point to point, and signals propagate from the header board to the receptacle board. Header Figure 1-6 Mezzanine Link SMA's Receptacle 1.4.4 EYE PATTERNS: PERFORMANCE FIGURE An eye pattern is a good indication of the receiver s ability to interpret signals correctly. It includes the effects of link loss, ISI (intersymbol interference), tramitter jitter, and system noise. To quantify the eye opening, we will use a performance mask based on the following two performance metrics (Figure 1-7) Normalized maximum eye opening height This height is the maximum eye opening height divided by the amplitude of the input signal. Normalized mask width when height is 25% of differential amplitude (W(H = 25%)). This represents the mask width (when the mask height is 25% of the differential amplitude) divided by the bit time. 1.4.2 CONNECTION DIAGRAM An interconnection link is defined as the path from the input test connection, through a short length of PCB, one connector footprint, a mated pair of mezzanine connectors, a second connector footprint, and a second short length of PCB, to the output test connection. Each mezzanine connector has unique tramission and reflection properties. A mezzanine connector system is typically comprised of two unique connectors; a plug and a receptacle. The contact design, although unique to the individual connector, is typically repeated by the number of positio in the connector. A connector section including only a few positio needs to be tested, as their performance is representative of the rest of the contacts. 1.4.3 MEZZANINE PCB PARAMETERS For the measurements reported in this booklet, the header and receptacle boards were fabricated with the same pad, via and trace design. All connectio were made by edge coupled differential striplines. All traces were designed to have a 100 Ω differential impedance. Only one board material was used for this testing: Rogers 4003 (Er=3.38 and d = 0.0027). The length of the traces on each board were 1.5 inches +/-.01. This is the trace length from the SMA to the BGA pad on each board. W = 40% & H = 25% Figure 1-7 Definition of performance figures for evaluating eye openings. In this booklet, we will use a mask height of 25% and a mask width of 40% as the acceptance criteria for all eye pattern measurements. 16

MEG-ARRAY CONNECTOR SYSTEM 3.5 PROPAGATION DELAY The propagation delay is the time needed for a signal to propagate through a connector pair. It is calculated as the difference in time between the tramitted 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.

MEG-ARRAY CONNECTOR SYSTEM 3.6 CROSSTALK Single-pair active crosstalk is the crosstalk measured at one pair 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. The multi-pair active crosstalk is the maximum crosstalk that can be measured at one pair of the connector when a signal is injected in other neighboring pairs of the connector. The multi-pair active crosstalk is calculated as the sum of the absolute values of the single-pair active crosstalk. This mea that the multi-pair active crosstalk must be interpreted as the absolute worst-case value. Figures 3-33 the 3-35 show Multi-Active NEXT for MEG-Array at 4mm, 10mm and 14mm board-to-board heights.
