Hi Hadi,

I sent this support need over email, please help me speed up this issue. Thanks.

Hi Shaoxing,

if the minimum is not met, it might be considered as start or stop.

Hi Hadi,

Currently customer this hold up timing is 200ns (less than 300ns), PMBUS commutations is normal. They want to give assess risk here, what is the minimum tolerance time? If this hold up timing is 100ns, or even low timing here, so PMBUS commutations must be abnormal. Do we have this similar data? Thanks. 

Hi Hadi,

Could you confirm the below th data hold up time 200ns? (Marked red lines) is there any risk here? Thanks.
