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.

SI Test and Measurement 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 0.8 GHz @ -15dB and ~0.5 to 0.9 Gbit/sec.
Differential:
DC to 1.4 GHz @ -10dB and ~0.9 to 1.5 Gbit/sec.
Single-ended: DC to 1.0 GHz @ -15dB and ~0.6 to 1.1 Gbit/sec.
Single-ended: DC to 2.0 GHz @ -10dB and ~1.3 to 2.1 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.

The eye opening sustains a Data Mask with a voltage swing of
±175mV @ 100psec period.
Single-ended Eye Diagrams were successfully formed at 5 Gbits/sec.,
with Jitter at 10psec and 19% eye closure.
The eye opening sustains a Data Mask with a voltage swing of
±125mV @ 140psec period.

• A Return Loss at -15dB (~18% Reflection) is the normally accepted industry standard. 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.

• A NeXT at 5% maximum is the normally accepted industry standard. Shown above are worst case values
for unshielded adjacent terminals. Under these conditions NeXT results are favorable.
• A FeXT at 2% maximum is the normally accepted industry standard. Shown above are worst case values
for unshielded adjacent terminals. Under these conditions FeXT results are very good.
• A successful Eye-opening was created at 5 Gbit/sec and is very 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%.
