DS90UH948-Q1: Adjusting LVDS drive strength

Akihiro Hirata

Part Number: DS90UH948-Q1

Hello team,

Regarding DS90UH948-Q1, my customer is asking if there is any feature which can adjust the LVDS drive strength to mitigate the EMI.

I don't think so but just want to confirm...

Thank you.

Regards,

LVDS drivers must generate a voltage drop of 350 mV over the 100 Ω load, so their drive strength is fixed.

To reduce EMI, add ferrite beads or a common-mode choke.

Hello Akihiro,

Yes, this is possible. Please refer to Table "6.5 DC Electrical Characteristics" on page 14, and look for VOD.
