Hi team.

I have One question.

Regarding,below's p.56 of C16,

http://www.ti.com/jp/lit/ug/snlu135b/snlu135b.pdf

It is MuRata GRM188R72A104KA35D CAP, CERM, 0.1 µF, 100 V, +/- 10%, X7R

please let me know why this board use a 100V withstand voltage.

Thanks.

Hi Maezeno,

The rating voltage of AC coupling cap. in the FPD-Link is used to reject the common-mode noise as this AC coupling is put in the connector side with cable medium. TI recommends that you can select higher rating voltage, typically >=50V is required.

For this EVM board, this is our BOM generation list for your reference, you also can use 50V rating voltage cap.

best regards,

Steven
