<Converting from email>

We're getting ready to start our first card design using the 25G Ethernet retimer. I found three different decoupling solutions in TI's documentation. Which one do you recommend we use?

Data sheet

----------

4 x 0.1 uF

2 x 1.0 uF

 

Schematics

----------

6 x 0.1 uF

1 x 1.0 uF

1 x  10 uF

 

Allegro brd file

----------------

1 x 0.1  uF 0402

2 x 0.22 uF 0201

5 x 0.1  uF 0201

    Hi,

    I would recommend using the solution shown in the EVM schematic.  I think there was likely a copy/paste issue with the footprints in the BRD file that are resulting in the inconsistent descriptions.  Our BOM file supports the EVM schematic file. 

    Thanks,

    Drew
