The MAX4888ETI+ is a 2.5Gbps PCI Express passive switch in 28 pin TQFN package. This high speed passive switch routes PCI Express (PCIe) data between two possible destinations. The MAX4888 is a quad single pole/double throw (4 x SPDT) switch and it is ideally suited for switching two half lanes of PCIe data between two destinations. The device has single digital control input (SEL) to switch signal paths. It is fully specified to operate from single 3V to 3.6V power supply and also operates down to 1.65V.
