DS90UB933-Q1EVM: Must be AC coupled with a 0.1-µF capacitor with 50V?

Part Number: DS90UB933-Q1EVM

Hi team,

My customer want to clarify if AC coupled capacitor shall be rated 50V. Customer want to use smaller size capacitor which has 16V, not 50V rating?

Is it possible? Regards, NY

More specifically speaking, in 933EVM user's guide, C17 (0.1uF) and C19 (0.047uF) are 50V rating cap.

Naoki,
as the ac coupling capacitor is used for blocking power supply delivered from de-ser, and it is used in the port side for hot swap insertion, please make sure this coupling capacitor can tolerate these. The 16V rating capacitor could be accepted if the link is safeguard.

best regards,
Steven
