LMH1297EVM: AC coupling capacitor at SDI_IO and SDI_OUT

K.Yaita

Part Number: LMH1297EVM

Hi Team,

LMH1297EVM uses AC coupling capacitor (C10, C11, C12, C13) with 4.7uF 10V capacitor.
Can my customer use these capacitor with 4.7uF 6.3V?
I believe it is okay however would like to confirm just in case.

Hi Yaita-San,

Your understanding this is correct. 10uF AC coupling caps would have even a lower DC wander and thus it should be fine.

Hi Nasser-san,

Thank you always for your support.
We can use 6.3V voltaging rating capacitor. Is it correct?

Hi Yaita-San,

Yes. This is within the range of the SDI input swing range.
