Hi Team,

I understood INTB pin outputs LOW when INTB_IN on deserializer is set LOW as the following.
Can INTB pin still output LOW if deserializer loses lock during interrupt condition?

Hello Yaita,
I verified on my bench setup and yes, the INTB on the 927 will stay LOW even even if the deserializer (in this case 928) loses LOCK. I removed the FPD3 cable and also tried PDB reset on the deserializer to cause an unlock condition.
