Hi Team,

Can the 3.3V LVDS signal directly connect to 947? I think it can't as VDDIO=1.8V. Right?

No, like you said 947 IO is at 1.8V level. 3.3V LVDS signal should not be connected directly yo 947.

Hi Charley,

Thanks for your reply. Is it usually solved by adding voltage translator to change 3.3V to 1.8V?

0 Charley Cai over 6 years ago in reply to Amelie Zheng

Yes, but please make sure the translator supports LVDS speed and has low jitter.

Best Regards,
