Product Details

The MAX4888B evaluation kit (EV kit) provides a proven design to evaluate the MAX4888B dual double-pole/double-throw (2 x DPDT) switch. The device is ideal for switching two half-lanes of PCI Express® (PCIe) data between two possible destinations and supports up to 8.0Gbps data rate (Gen III PCIe). The 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 EV kit PCB comes with a MAX4888BETI+ installed, which is available in a lead(Pb)-free, 28-pin (3.5mm x 5.5mm) TQFN package with an exposed pad. The EV kit circuit requires a 3.3V power supply capable of supplying at least 100mA.
