1.27mm Pitch B2B® SMT Connector 8.00mm Mated Height SIGNAL INTEGRITY SIMULATION AND MODELING Rev. 1 www.advanced.com Advanced Interconnections Corp. 5 Energy Way, West Warwick, RI 02893 USA 401.823.5200 • 800.424.9850 • Fax: 401.823.8723 Signal Integrity Data Reporting At Advanced Interconnections Corporation, our Signal Integrity reporting method differs dramatically from the common industry practice of isolating the aggressor and victim terminals from each other by introducing dedicated ground terminals between them. We believe this method represents a theoretical, best-case, scenario that does not serve the needs of most systems engineers and circuit designers. An unrealistic number of connector terminals must be assigned to ground in order to achieve this scenario. Our standard reporting practice is closely aligned with the decision-making processes of most systems engineers and circuit designers. The reported data addresses our customers I/O assignments (net-list) and helps them determine where to best run highversus-low frequency signals through our connectors. As such, our reporting method represents a more practical net-list scenario. Utilizing our unbiased SPICETM and IBISTM files, system designers are able to create and/or debug their net-list quickly and accurately.

A pin-out of 3 rows and 4 columns was assigned from a 4x4 array: Leads added to stabilize signal launch were de-embedded S1GND S1+ GND • GND S1GND GND S2+ GND GND S2GND A total of 12 sections were implemented, 6 for the female receptacle and 6 for the male pin. Each section was implemented using 3 separate horizontal rows, which then were combined together into the 3x4 array using the ADS “combine 3 into 1” element. The material properties of the plastic bodies were as follows: Male: Er = 3.7, Loss Tan = 0.005; and Female: Er = 3.2, Loss Tan = 0.009. Air was defined as Er = 1, Loss Tan = 0. The Effective Er (composite value = plastic + air) of Receptacle_plastic_2 was calculated to be Eff_Er = 2.75, Loss Tan = 0.005.

Rev. 1 S1+ De-embedded Waveguide Ports SI Modeling & Simulation Study Simulation Results The test and measurement tasks were completed and the recommended Operational Bandwidth for the Socket Adapter System is as follows: Differential: DC to 1.3 GHz @ -15dB and ~0.8 to 1.4 Gbit/sec. Differential: DC to 2.5 GHz @ -10dB and ~1.6 to 2.6 Gbit/sec. Single-ended: DC to 2.1 GHz @ -15dB and ~1.3 to 2.2 Gbit/sec. Single-ended: DC to 4.6 GHz @ -10dB and ~2.9 to 4.9 Gbit/sec.

Most applications will tolerate data at -10 dB (~32% Reflection), however in this instance, performance safety margins may be increased by de-rating the connectors Operational Bandwidth and Data Rate. • A Insertion Loss at -3dB (~50% of applied Power & ~71% of applied Voltage arrives at the Output Port) is the normally accepted industry standard. • An Effective Impedance of 100Ω ±10Ω for Differential and 50Ω ±5Ω for Single-ended is the normally accepted industry guideline. De-rating the signal input risetime will improve the above Zo values.

Shown above are worst case values for unshielded adjacent terminals. Under these conditions the NeXT differential results are acceptable. •A FeXT at 2% maximum is the normally accepted industry standard. Shown above are worst case values for unshielded adjacent terminals. Under these conditions differential FeXT results are acceptable and the single-ended FeXT results are acceptable. • A successful Eye-opening was created at 5 Gbit/sec and is favorable as this data rate is well within the Operational Bandwidths recommended for this connector system. See note below. NOTE: The connector’s transmit Data Mask can be defined to quantify the effective performance of the eye formation. For a Differential data mask, the total voltage equals 35% of the eye’s applied peak-to-peak voltage, (1V in this report), and its period equals 50% of the Eye Interval, (200psec in this report). For a Single-ended data mask, the total voltage equals 50% of the eye’s applied peak-to-peak voltage, (500mV in this report), and its period equals 70% of the Eye Interval, (200psec in this report). The Eye Interval = 1/Eye Data Rate = 1/5E9 = 200psec in this report. Normally, Maximum allowable Jitter = 5% and Maximum allowable Eye-Closure = 12%.
