TDP2004: Lane and Polarity Swapping

Part Number: TDP2004
Other Parts Discussed in Thread: TMUXHS4612

Tool/software:

Hi,

Does TDP2004 support lane swapping? e.g. swap D0A with D3A.

Does TDP2004 support polarity swapping within a pair? e.g. swap D0+A with D0-A.

    Hi Dan,

    Because TDP2004 is a linear redriver, as long as both inputs and output lanes are swapped and polarity is swapped, this device supports both polarity and lane swapping.

    Best,

    Thanks J, that's great news!

    This is really important because I plan to use TMUXHS4612 with TDP2004, and their pin maps don't align in a way that's easy to route without exceeding via count and other signal integrity guidelines.

    Kind regards,
    Dan

    Hi Dan, 

    TMUXHS4612 should also support lane and polarity swapping as long as the input and the output matches since this device is a passive mux. 

    Best,
