Part Number: SN65LVDS822

Hi,Expart.

Can I get any advices?
Now, my customer will try to using SN65LVDS822.
Since it is experimenting for ESD air discharge.

When using LVDS 822, It caused horizontal stripes on the screen about once in 10 times.
It is not a critical problem.
Our customer is trying to avoid by countermeasures by surrounding mechanisms,
Is there anything else we can suggest to my customer?
Please tell me the general theory.

Best regards.
Ryuji

    Hello Ryuji,
    Because the TI LVDS devices has direct ESD protection pins on the bus pins, we not have any additional recommendation on this matter, however, please check the power supply railes for the device, including filtering. Also check if ground chasis in needed and or well installed in your application.

    Regards,
