The MAX4889B evaluation kit (EV kit) provides a proven design to evaluate the MAX4889B PCI Express® (PCIe) Gen II 5.0Gbps passive switch. The MAX4889B is a quad double-pole/double-throw (4 x DPDT) switch ideal for switching four half lanes of PCIe data between two destinations. The MAX4889B EV kit is used for critical tests (e.g., eye diagrams and s-parameter measurements such as insertion loss, return loss, and off-isolation).
The MAX4889B EV kit PCB comes with a MAX4889BETO+ installed. The MAX4889BETO+ is available in a lead(Pb)-free 3.5mm x 9.0mm, 42-pin TQFN package with an exposed pad.
The MAX4889B EV kit can also be used to evaluate the MAX4889C. Contact the factory for a free sample of the pin-compatible MAX4889CETO+.
