Hi team,

In TI_LMH1219_LMH1226_IBIS_AMI_User_Guide.pdf , S port sequence is 1->2, 3->4. but in tx_term0-7.s4p, S port sequence is 1->3, 2->4. which is correct?

Thanks!

Hi Rayna,

Typically pkg model port numbering (1->2, and 3->) is different from s4p(1->3 and 2->4). Please follow example schematic.

Hi Nasser,

I didn't get it. which example schematics should follow? Why pkg model port numbering (1->2, and 3->4) is different from s4p(1->3 and 2->4)? which should customer use in application?

Hi Ruixin,

Please let the customer know to use the example in the IBIS AMI folder. The pkg model port number is 1->2 and 3->4. If the customer has ans4p file of 1->3 2->4 they should remeasure with the setting of 1->2 3->4 if possible.

Best Regards,

Nick
