Description

The MAX4888B/MAX4888C dual double-pole/double-throw (2 x DPDT), high-speed passive switches are ideal for switching two half-lanes of PCI Express® (PCIe) data between two possible destinations. These devices feature a dual digital control input to switch signal paths. The MAX4888C is intended for use in systems where both the input and output are capacitively coupled (e.g., SAS, SATA, XAUI, and PCIe) and provides a 10µA (typ) source current and a 60kΩ (typ) internal biasing resistor to GND at the AOUT_ and BOUT_ pins.

The devices are fully specified to operate from a single +3.3V (typ) power supply. Both devices are available in an industry-standard 3.5mm x 5.5mm, 28-pin TQFN package. They operate over the -40°C to +85°C extended temperature range.
