11-118r0 Multi-Function Connector Proposal

2. Connector Selection Criteria
Support both enterprise and client PCI Express sideband signaling requirements
Interoperability with legacy interfaces (SAS, SATA and new Multilink)
Dual domain support
Crosstalk between new and legacy pins
Deteriorated channel performance with addition of new pins
Power Consumption

5. 11-118r0 Multi-Function Connector Proposal
Mechanical Details
Utilize existing contact design and pitch for new main section signals ( pins)
Ensures mechanical interoperability with legacy SATA, SAS and new Multilink
Two pairs of 100MHz differential clock added at ends of connector to support dual domain (6 pins)
Accommodates additional sideband pins in PCI Express edge connector interface

6. Multi-Function Signal Assignments
Sidebands located on pins E1 to E10 and E25 to E33
Pins E29 to E33 shared with multilink
Header post location for clocks to address crosstalk concerns with legacy primary port
