The MAX4888A/MAX4889A high-speed passive switches route PCI Express® (PCIe) data between two possible destinations. The MAX4888A is a quad single-pole/double-throw (4 x SPDT) switch ideally suited for switching two half lanes of PCIe data between two destinations. The MAX4889A is an octal single-pole/double-throw (8 x SPDT) switch ideal for switching four half lanes of PCIe data between four destinations. The MAX4888A/MAX4889A feature a single digital control input (SEL) to switch signal paths.

The MAX4888A/MAX4889A are fully specified to operate from a single +3.0V to +3.6V power supply††. The MAX4888A is available in a 3.5mm x 5.5mm, 28-pin TQFN package. The MAX4889A is available in a 3.5mm x 9.0mm, 42-pin TQFN package. Both devices operate over the -40°C to +85°C temperature range.

Product Details

The MAX4889A evaluation kit (EV kit) provides a proven design to evaluate the MAX4889A PCI Express® (PCIe) Gen II 5.0Gbps passive switch. The MAX4889A is an octal single-pole/double-throw (8 x SPDT) ideal for switching four half lanes of PCIe data between four destinations. The MAX4889A EV kit is used for critical tests (i.e., eye diagrams and s-parameter measurements such as insertion loss, return loss, and off-isolation).

The MAX4889A EV kit PCB comes with a MAX4889AETO+ installed. The MAX4889AETO+ is available in a lead-free 3.5mm x 9.0mm, 42-pin TQFN package.
