PCI Express^® Flip CEM Card Edge Connectors

EXTEND DIFFERENTIAL SIGNALING TO 32GT/S NRZ

The PCIe^® Gen 5 Flip CEM is a new 1.0mm pitch vertical card edge connector that follows PCIe^® standard mating interface. It is designed with a different footprint because the contacts are “JJ” type or “LL” contacts which provide maximum savings of up to 19.5% in keepout area. The current Flip CEM supports 32GT/s (Gen 5) and the mating side supports backward compatibility with PCIe^® 4/3/2/1 card.

The Flip CEM is ideal for use when the PCIe^® connector has to be placed close to the PCB board edge. The Flip CEM connector with “JJ” or “LL” contacts can avoid the trace from going inside the connector which causes stub.
