DOCUMENT SCOPE
This document uses modeled connector data (SP-170382-0001.s8p and SP-170382-0001_revB.s8p) to
demonstrate conformance to the SFF-8081 revision 0.9 specification. Information about these models can be found
in Electrical Model Documentation (EE-170382-001_rev3.pdf and EE-170382-0001_revB.pdf) for these modeled
data.
For the differential requirements the defined SFF-8081 reference board losses, shown below, were added to the
modeled connector data. Note, that SFF does not define any common mode insertion losses for the applicable test
fixtures. There for no adjustments were made to the connector only common mode data to show conformance.
Actual measured values would vary depending on the common mode insertion loss performance of the test fixtures.
