TVP5151: ESD protection for video input

Part Number: TVP5151

We burned some video decoders during ESD tests of our devices according to ISO 10605-2008.
What TI recommended for ESD protection of TVP5151?
In datasheet provided:

G. System level ESD protection is not included in this application circuit, but it is highly recommended on the analog
video inputs.

But i can't found any recommendations about it.
I found recommendation from Littelfuse http://www.littelfuse.com/technical-resources_old/application-designs/circuits/svideo.aspx

But there are only one p/n and we have doubts about appropriate this device to TVP5151.
Can we get recommendations for this case from TI?

  • Dear Customer,

    I moved your post to this forum. Products covered in this forum are Legacy NTSC/PAL Decoders (TVP5xxx) Video ADCs (TVP7xxx) Video DACs (THS8xxx). TI does not recommend using these parts in a new design (NRND). Support for these devices is extremely limited.

    best regards,
    David Zhou
  • I would suggest any low capacitance protection that provides clamping at around +-5V.

    If the protection is provided at the connector (which it should be) then make sure it is bi-directional since the video input signal could extend below ground.

  • Hello All,
    this issue was going out when we made some modifications in PCB routing and add some ESD protections.
