Description: Surface Mount Terminal Strip 2.54mm Pitch, 7.47 mm (0.294”) stack height Connector Overview Surface Mount Terminal Strip series (TSM) are capable of mating to SSW, BCS, SSM, IDSS, IDSD, SLW, CES and HLE series. TSM and Socket Strip (HLE) are available with up to 72 pins for TSM series and 100 pins for HLE series. The mated connector achieves up to 72 I/Os with 7.47mm (0.294") stack height. The data in this report is applicable only to the TSM mates to HLE. Connector System Speed Rating TSM/HLE Surface Mount Strip 2.54mm Pitch, 7.47 mm (0.294”) stack height Signaling Speed Rating Single-Ended: 4.5GHz/ 9Gbps Differential: 13.5GHz/ 27Gbps 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 a short length of trace loss 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 connector pair and footprint effects on a typical multi-layer PCB. PCB effects (trace loss) are de-embedded from test data. Board related effects, such as pad-to-ground capacitance, are included in the data presented in this report. Additionally, intermediate test signal connections can mask the connector’s true performance. Such connection effects are minimized by using high performance test cables and adapters. Where appropriate, calibration and de-embedding 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. However, dedicating pins to ground reduces signal density of a connector. Therefore, care must be taken when choosing signal/ground ratios in cost or density-sensitive applications.

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. However, in most applications, performance can safely be considered equivalent. Signal Edge Speed (Rise Time): In pulse signaling applications, the perceived performance of the interconnect can vary significantly depending on the edge rate or rise time of the exciting signal. For this report, the fastest rise time used was 30 ps. Generally, this should demonstrate worstcase 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 500 ps. For this report, measured rise times were at 10%-90% signal levels.

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 S-Parameters, 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 directly from network analyzer measurements. Time Domain Data Time Domain parameters indicate Impedance mismatch versus length, signal propagation time, and crosstalk in a pulsed signal environment. The measured S-Parameters from the network analyzer are post-processed using Agilent Advanced Design System to obtain the time domain response. Time Domain procedure 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. In this report, propagation delay is defined as the signal propagation time through the connector and connector footprint. It includes 27 mils of PCB trace on the TSM connector side and 67 mils of trace on the HLE PCB. Delay is measured at 30 picoseconds signal risetime. Delay is calculated as the difference in time measured between the 50% amplitude levels of the input and output pulses. Crosstalk or coupled noise data is provided for various signal configurations. 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. However, modern system crosstalk tolerance can vary greatly.

The part numbers are TSM-130-04-L-DV-A and HLE-130-02-G-DV. The TSM/ HLE Series connector are surface mount products. The TSM/HLE Series socket uses a strip contact system. Each connector has two rows of contacts evenly spaced on a 2.54 mm (0.100”) pitch. A photo of the test articles mounted to SI test boards is shown below. Test System Description The test fixtures are composed of four-layer FR-4 material with 50Ω signal trace and pad configurations designed for the electrical characterization of Samtec high speed connector products. A PCB mount SMA connector is used to interface the VNA test cables to the test fixtures. Optimization of the SMA launch was performed using full wave simulation tools to minimize reflections. Six test fixtures are specific to the TSM/HLE Series connector set and identified by part numbers PCB-103152-TST-01, 03, 05, 09, 10, and 11. Calibration standards specific to the TSM/ HLE Series are located on the calibration boards PCB-103152-TST-07 and PCB-103152-TST-08. To keep trace lengths short, three different test board sets were required to access the necessary signal pins. PCB-103152-TST-XX Test Fixtures Shown below is a photograph of one of the three test board sets.

The calibration board is shown below. Prior to making any measurements, the calibration board is characterized to obtain parameters required to define the calibration kit. Once a cal kit is defined, calibration using the standards on the calibration board can be performed. Finally, the device can be measured and the test board effects are automatically removed.

The TRL calibration effectively removes 1.4” of test board trace effects. Since the pad sizes for the TSM and HLE connectors are different sizes the reference plane location is slightly different on each test board. This means that 27 mils of test board trace length effects for the TSM connector side and 67 mils for the HLE connector side are include in the measurement. The S-Parameter measurement includes: ABCDE- The TSM Series connector set Test board vias, pads (footprint effects) for the TSM connector side. 27 mils of 16 mil wide microstrip trace.

For this reason, extreme care is taken in the design of the LRM calibration standards, the SI test boards, and the selection of the PCB vendor. The measurement process begins with a measurement of the LRM calibration standards. A coaxial SOLT calibration is performed using an N4433A ecal module. This measurement is required in order to obtain precise values of the line standard offset delay and frequency bandwidths. Measurements of the reflect and 2x through line standard can be used to determine the maximum frequency for which the calibration standards are valid. For the TSM/ HLE Series test boards, this is greater than 20 GHz. From the LRM calibration standard measurements, a user defined calibration kit is developed and stored in the network analyzer. Calibration is then performed on all 4 ports following the calibration wizard within the Agilent N5230C. This calibration is saved and can be recalled at any time. Calibration takes roughly 30 minutes to perform. Time Domain Procedures Mathematically, Frequency Domain data can be transformed to obtain a Time Domain response. Perfect transformation requires Frequency Domain data from DC to infinity Hz. Fortunately, a very accurate Time Domain response can be obtained with bandwidth-limited data, such as measured with modern network analyzer. The Time Domain responses were generated using Agilent ADS 2009 update 1. This tool has a transient convolution simulator, which can generate a Time Domain response directly from measured S-Parameters. An example of a similar methodology is provided in the Samtec Technical Note on domain transformation http://www.samtec.com/Technical_Library/reference/articles/pdfs/tech-note_usingPLTS-for-time-domain-data_web.pdf Impedance (TDR) A step pulse is applied to the touchstone model of the connector and the reflected voltage is monitored. The reflected voltage is converted to a reflection coefficient and then transformed into an impedance profile. All ports of the Touchstone model are terminated in 50 ohms.

A step pulse is applied to the touchstone model of the connector and the transmitted voltage is monitored. The same pulse is also applied to a reference channel with zero loss, and the Time Domain pulses are plotted on the same graph. The difference in time, measured at the 50% point of the step voltage is the propagation delay. Near-End Crosstalk (TDT) & Far End Crosstalk (TDT) A step pulse is applied to the touchstone model of the connector and the coupled voltage is monitored. The amplitude of the peak-coupled voltage is recorded and reported as a percentage of the input pulse.
