Tool/software:
I am using the DP83TC812SRHARQ1 on one of my products which is currently going through ESD testing. From pin 12/13 of the part to the connector, my schematic is the same as your example schematic on the development board. I am seeing some ESD failures with this part that I am debugging. In the datasheet, I saw that it says it is qualified to “ IEC61000-4-2 ESD classification level 4 for pins 12 and 13: ±8-kV contact discharge”. Does this mean that the link stays active and link loss counter doesn’t increase for that test? Or just that the part doesn’t fail in mode that causes permanent damage?
The failures I am seeing is that the link loss counter incrementing on address 0x561. The link is active right after the ESD pulse, it just looks to briefly drop out. My testing criteria is the same as IEC61000-4-2 ESD classification level 4 at 8kv.
