Data subject to change without notice. Rev. 0 De-embedded Waveguide Ports S1+ SI Modeling & Simulation Study Performance Results • The test and measurement tasks were completed and the recommended Operational Bandwidth for the Socket Adapter System is as follows: Differential: DC to 3.10 GHz @ -15dB and ~2.0 to 3.3 Gbit/sec. Differential: DC to 10.0 GHz @ -10dB and ~6.4 to 10.7 Gbit/sec. Single-ended S1+: DC to 8.0 GHz @ -16dB and ~5.1 to 8.5 Gbit/sec. Single-ended S1-: DC to 8.0 GHz @ -13dB and ~5.1 to 8.5 Gbit/sec. • At the above Bandwidths, the Impedance of this connector system is low. This has been attributed to the geometry of the female shell and the proximity of adjacent terminals.

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.

Some customers may specify a value as low as 2% maximum for this attribute. NeXT results are good. • A FeXT at 2% maximum is the normally accepted industry standard. Some customers may specify a value as low as 1% maximum for this attribute. FeXT results are excellent. • A successful Eye-opening was created at 5 Gbit/sec and is excellent as this data rate is well within the Operational Bandwidths recommended for this connector system. See note below. NOTE: It’s not practical to define pass-or-fail criteria for Jitter and Eye-Closure. However, guidelines for 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 risetime, (200psec in this report). For a Single-ended data mask, the total voltage equals 50% of the eye’s applied peak-topeak voltage, (500mV in this report), and its period equals 70% of the risetime, (200psec in this report).
