Description: Vertical Surface Mount, 0.635mm (.025”) Pitch, Mates w/ 1.60mm (.062”) card Connector Overview Micro 0.635 mm (.025”) pitch interfaces (MEC6 Series) are double row structures with up to 70 contacts per row. The MEC6 connector is available in a vertical and right angle body style. Connector styles both have the 1.60mm (.062”) edge card thickness mating option. Applications can include board-to-board via riser edge card or cable-to-board. Electrical characteristics reported are specific to the.635mm pitch, MEC6 vertical surface mount connector mated with a 1.60mm ) thickness edge card. Connector System Speed Rating MEC6 Series, 0.635mm (.025”) Pitch Interface, Vertical Surface Mount Signaling Speed Rating Single-Ended: Differential: 7.5 GHz / 15 Gbps 7.0 GHz / 14 Gbps The Speed Rating is based on the -3 dB insertion loss point of the connector system. The -3 dB point can be used to estimate usable system bandwidth in a typical, two-level signaling environment. To calculate the Speed Rating, the measured -3 dB point is rounded up to the nearest half-GHz level. The up-rounding corrects for a portion of the test board’s trace loss, since trace losses are included in the loss data in this report. The resulting loss value is then doubled to determine the approximate maximum data rate in Gigabits per second (Gbps). For example, a connector with a -3 dB point of 7.8 GHz would have a Speed Rating of 8 GHz/ 16 Gbps. A connector with a -3 dB point of 7.2 GHz would have a Speed Rating of 7.5 GHz/ 15 Gbps.

All efforts are made to reveal typical best-case responses inherent to the system under test (SUT). In this report, the SUT includes the test PCB from drive side probe tips to receive side probe tips. PCB effects are not removed or de-embedded from the test data. PCB designs with impedance mismatch, large losses, skew, cross talk, or similar impairments can have a significant impact on observed test data. Therefore, great design effort is put forth to limit these effects in the PCB utilized in these tests. Some board related effects, such as pad-to-ground capacitance and trace loss, are included in the data presented in this report. But other effects, such as via coupling or stub resonance, are not evaluated here. Such effects are addressed and characterized fully by the Samtec Final Inch® products. Additionally, intermediate test signal connections can mask the connectors’ true performance. Such connection effects are minimized by using high performance test cables, adapters, and microwave probes. Where appropriate, calibration and deembedding routines are also used to reduce residual effects. Differential and Single-Ended Data Most Samtec connectors can be used successfully in both differential and single-ended applications. However, electrical performance will differ depending on the signal drive type. In this report, data is presented for both differential and single-ended drive scenarios. Connector Signal to Ground Ratio Samtec connectors are most often designed for generic applications, and can be implemented using various signal and ground pin assignments. In high speed systems, provisions must be made in the interconnect for signal return currents. Such paths are often referred to as “ground”. In some connectors, a ground plane or blade, or an outer shield is used as the signal return, while in others; connector pins are used as signal returns. Various combinations of signal pins, ground blades, and shields can also be utilized. Electrical performance can vary significantly depending upon the number and location of ground pins. In general, the more pins dedicated to ground, the better electrical performance will be. But dedicating pins to ground reduces signal density of a connector. So care must be taken when choosing signal/ground ratios in cost- or density-sensitive applications.

Only one single-ended signal or differential pair was driven for crosstalk measurements. Other configurations can be evaluated upon request. Please contact [email protected] for more information. In a real system environment, active signals might be located at the outer edges of the signal contacts of concern, as opposed to the ground signals utilized in laboratory testing. For example, in a single-ended system, a pin-out of “SSSS”, or four adjacent single ended signals, might be encountered, as opposed to the “GSG” and “GSSG” configurations tested in the laboratory. Electrical characteristics in such applications could vary slightly from laboratory results. But in most applications, performance can safely be considered equivalent.

For this report, the fastest rise time used was 30 +/-5 ps. Generally, this should demonstrate worst case performance. In many systems, the signal edge rate will be significantly slower at the connector than at the driver launch point. To estimate interconnect performance at other edge rates, data is provided for several rise times between 30 ps and 1.0 ns. For this report, rise times were measured at 10%-90% signal levels. Frequency Domain Data Frequency domain parameters are helpful in evaluating the connector system’s signal loss and crosstalk characteristics across a range of sinusoidal frequencies. In this report, parameters presented in the frequency domain are insertion loss, return loss, and near-end and far-end crosstalk. Other parameters or formats, such as VSWR or Sparameters, may be available upon request. Please contact our Signal Integrity Group at [email protected] for more information. Frequency performance characteristics for the SUT are generated from time domain measurements using Fourier Transform calculations. Procedures and methods used in generating the SUT’s frequency domain data are provided in the frequency domain test procedures in Appendix E of this report. Time Domain Data Time Domain parameters indicate impedance mismatch versus length, signal propagation time, and crosstalk in a pulsed signal environment. Time Domain data is provided in Appendix E of this report. Parameters or formats not included in this report may be available upon request. Please contact our Signal Integrity Group at [email protected] for more information. Reference plane impedance is 50 ohms for single-ended measurements and 100 ohms for differential measurements. The fastest risetime signal exciting the SUT is 30 ± 5 picoseconds. In this report, propagation delay is defined as the signal propagation time through the PCB connector pads and connector pair. It does not include PCB traces. Delay is measured at 30 ± 5 picoseconds signal risetime. Delay is calculated as the difference in time measured between the 50% amplitude levels of the input and output pulses.

All measurements are single disturber. Crosstalk is calculated as a ratio of the input line voltage to the coupled line voltage. The input line is sometimes described as the active or drive line. The coupled line is sometimes described as the quiet or victim line. Crosstalk ratio is tabulated in this report as a percentage. Measurements are made at both the nearend and far-end of the SUT. Data for other configurations may be available. Please contact our Signal Integrity Group at [email protected] for further information. As a rule of thumb, 10% crosstalk levels are often used as a general first pass limit for determining acceptable interconnect performance. But modern system crosstalk tolerance can vary greatly.

Four bays of the CSA8000 are occupied with three Tektronix 80E04 TDR/Sampling Heads and one Tektronix 80E03 Sampling Head. Time domain results are generated using the TDR/Sampling Head capability. S-parameter data is generated from a TDR based software tool called I-Connect Probing is accomplished using a video microscopy system, microprobe positioners, and 40GHz capable probes (Figure 5). The 450 micron pitch probes are located to PCB launch points with 25X to 175X magnification and XYZ fine positioning adjustments available from both the probe table and micro-probe positioners. Electrically the microwave probes rate a < 1.0 dB insertion loss, a ≥18 dB return loss, and an isolation of 38 dB providing high-bandwidth and low parasitic measurement results. Combined, the above technology provides a stable measurement environment along with the electrical accuracies for obtaining precise calibrations and signal launch capabilities (Figure 6).

This means that the operator, being extremely aware, can obtain SI time and frequency characteristics in an almost simultaneous fashion. Since IConnect setup procedures are specific to the frequency information sought, it is mandatory that the sample preparation and CSA8000 functional setups be consistent throughout the waveform gathering process. If the operators test equipment permits recall sequencing between the various test parameter setups, it insures IConnect functional setups remain consistent with the TDR/TDT waveforms previously recorded. Related time and frequency test parameter data recorded for this report were gathered simultaneously. Frequency (S-Parameter) Domain Procedures Frequency data extraction involves two steps that first measure the frequency related time domain waveform followed by post-processing of the time domain waveforms into loss and crosstalk response parameters versus frequency. The first step utilizes the Tektronix CSA8000 time based instrument to capture frequency related single-ended or differential signal types propagating through an appropriately prepared SUT. The second step involves a correlation of the time based waveforms using the TDA Systems IConnect software tool to post-process these waveforms into frequency response parameters. TDA Systems labels these frequency related waveform relationships as the Step and DUT reference. This report establishes the setup procedures for defining the Step and DUT reference for frequency parameters of interest. Once established, the Step and DUT references are post-processed in IConnect’s S-parameter computations window. CSA8000 Setup Listed below are the CSA 8000 functional menu setups used for single-ended and differential frequency response extractions. Both signal types utilize I-Connect software tools to generate S-parameter upper and lower frequency boundaries along with the step frequency. These frequency boundaries are determined by a time domain instruments functional settings such as window length, number of points and averaging capability. Once window length, number of points and averaging functions are set, maintain the same instrument settings throughout the extraction process.

For this series of tests, TDR methods are employed for the impedance and propagation delay measurements. Crosstalk measurements utilize TDT methods. The Tektronix 80E04 TDR/ Sampling Head provide both the signaling type and sampling capability necessary to accurately and fully characterize the SUT. Impedance The signal line(s) of the SUT’s signal configuration is energized with a TDR pulse. The far-end of the energized signal line is terminated in the test systems characteristic impedance (e.g.; 50Ω or 100Ω terminations). By terminating the adjacent signal lines in the test systems characteristic impedance, the effects on the resultant impedance shape of the waveform is limited. For signal launch and monitoring path guidelines reference table 8. Propagation Delay This test reports differential or single ended signal delay as the measured difference of propagation between a referenced length of the signal pads and signal traces (30 ± 5 ps edge rate) and the device under test (DUT) plus the electrical length of the signal pads and signal traces (PDpads/traces- PDDUT + PDpads/traces). PDpads/traces is the referenced physical length of PCB signal pads & traces equaling the PCB pads & traces entering and leaving the device under test (DUT). These measurable reference lengths (i.e.; SE_THRU1 to SE THRU2 & DIFF_THRU1 to DIFF_THRU2) are featured on PCB100487-TST-01 in Figure 3. The PDDUT + PDpads/traces variable is the mated MEC6 vertical surface mount connector card with pads & traces plus the edge card with pads & signal traces. Both PDpads/traces & PDDUT + PDpads/traces waveform edgerates are measured and recorded at 50 % amplitude of each recorded rising edge. The distance in time between the rising edges is the propagation delay of the device under test. In this case the propagation delay is that of the MEC6 connector (PDDUT). For signal launch and monitoring path guidelines reference table 8. Crosstalk An active pulsed waveform is transmitted through a selected SUT signal line. The adjacent quiet signal lines are monitored for the coupled energy at the near-end and far-end. Active and quiet lines not being monitored are terminated in the test systems characteristic impedance. Signal lines adjacent to the quiet lines remain terminated on both ends throughout the test sequence. Failing to terminate the active near or far end, quiet lines, or in some cases, signal lines adjacent to the quiet line may have an effect on amplitude and shape of the coupled energy. Measure the worse and best case in row coupling scenarios. Also measure the direct coupling effects that occur across a row of terminals.
