Hi,

One of our customer is using MLVDS buffer DS91M040 for backplane clock applications (ATCA compatible). Now when line card having DS91 is not powered then will there be any issue even if backplane clock is coming to this IC while it is not powered up? Will the internal ESD diodes will be creating any issues if the Input Signal is available but not the Power supply to this device? Please clarify.

 

Purna.
