PCIe, Single Lane, 2:1/1:2 Multiplexer and Redriver with Equalization

The MAX4969 active 2:1 and 1:2 multiplexer equalizes and redrives PCIe® signals up to 5.0GT/s (Gigatransfers per second) and operates from a single +3.3V supply.

The MAX4969 features PCIe-required electrical idle and receiver detection on each channel and improves signal integrity at the receiver through independent programmable input equalization and output deemphasis.

The MAX4969 is available in a small, 42-pin (3.5mm x 9.0mm) TQFN package optimal for simplified layout and space-saving requirements. The MAX4969 is specified over the 0°C to +70°C commercial operating temperature range.
