Multi-Function Connector Proposal (11-118r0) Barry Olawsky (3/7/2010) 11-118r0 Multi-Function Connector Proposal
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 11-118r0 Multi-Function Connector Proposal
PCI Express Sideband Requirements Single Domain 11-118r0 Multi-Function Connector Proposal
PCI Express Sideband Requirements Dual Domain 11-118r0 Multi-Function Connector Proposal
11-118r0 Multi-Function Connector Proposal Mechanical Details Utilize existing contact design and pitch for new main section signals (23 + 10 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 11-118r0 Multi-Function Connector Proposal
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 First mate: P4, P12 Second mate: S1, S4, S7, S8, S11, S14, P5, P6, P10, E11, E14, E17, E18, E21, E24, H2, H5 Third mate: All others 11-118r0 Multi-Function Connector Proposal
