Maxim MAX4889 Manuals

The MAX4888/MAX4889 are high-speed passive switches that route PCI Express® (PCIe) data between two possible destinations. The MAX4888 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 MAX4889 is an octal single-pole/double-throw (8 x SPDT) switch ideal for switching four half lanes of PCIe data between four destinations. The MAX4888/MAX4889 feature a single digital control input (SEL) to switch signal paths. The MAX4888/MAX4889 are fully specified to operate from a single 3.0V to 3.6V power supply and also operate down to +1.65V. The MAX4888 is available in a 3.5mm x 5.5mm, 28-pin TQFN package. The MAX4889 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.

The MAX4888/MAX4889 are high-speed passive switches used to route PCI Express data between two destinations. The MAX4888 is suitable for switching two half lanes of PCIe data, while the MAX4889 is suitable for switching four half lanes of PCIe data. They feature a single digital control input, support power supply voltage from 1.65V to 3.6V, and have low skew and low quiescent current.
