MAX4889BETO+ Description

Short technical summary and product information.

The MAX4889BETO+ is a quad double-pole/double-throw (DPDT) passive switch from Analog Devices, engineered for routing PCI Express (PCIe) data in desktop and notebook PCs. This device is ideal for switching four half lanes of PCIe data between two destinations, supporting PCIe Gen I, Gen II, and Gen III data rates.

 

It operates from a single +3.3V power supply and features superior return loss, better than -10dB at 5.0GHz. The MAX4889BETO+ has 8 channels with an on-resistance of 7 Ohms (typical). It is specified for an extended temperature range of -40°C to +85°C.

 

The switch is housed in a compact 3.5mm x 9.0mm, 42-pin TQFN-EP package, suitable for surface mount applications. Its applications include desktop PCs, notebook PCs, servers, and video graphics cards supporting SLI and CrossFire technologies.

 

This device utilizes a single digital control input (SEL) to switch signal paths, simplifying system design. The MAX4889BETO+ is designed for high-speed data transmission, ensuring signal integrity for demanding applications.
