FEATURES AND SPECIFICATIONS 0.75mm (.030”) Pitch AMC.0 B+ 170-Circuit Connectors footprint further reduces crosstalk by managing inter-pair affinity and incorporating additional ground vias for isolation. As a result, the AMC.0 B+ connectors achieve crosstalk of less than 3 percent at 12.5 Gbps. Three versions of the Molex AMC.0 B+ connector exist: the standard connector with locating pegs (series 75800), connector without pegs (series 75908) and the 1.15mm (.045”) extended-height connector (series 75791). This taller height is optimized for blade-server applications where cooling is critical. AMC.0 B+ connectors from Molex support the next generation of mezzanine card standards and 12.5 Gbps speeds The 170-circuit AMC.0 B+, or AdvancedMCTM connectors from Molex support the next generation of mezzanine card standards that allow for hot-plugging of high-speed serial interconnects. These connectors support AdvancedTCA (Advanced Telecommunications Computing Architecture), a standard developed by PICMG (PCI Industrial Computer Manufacturers Group). Molex AMC.0 B+ connectors feature controlled impedance and reduced crosstalk, plus a footprint launch optimized for high-speed data rates. This design enables the connector to achieve 12.5 Gbps NRZ (Non Return to Zero) signal transmission.
