MAX4969
PCIe, Single Lane, 2:1/1:2 Multiplexer and Redriver with Equalization
Allows the System to Support PCIe 2.0 Data Rates (Up to 5.0Gbps) Over Long Cables and Boards
|
Status
Active: In Production.
Description
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.
