Dear FvM,

thanks for answer!

when I said termination, I mean parallel termination like Pull-Up to half of power supply in bank!

In all application signed this only off-chip termination on Pcb, also signed that is on-chip parallel termination (VTT) available only GZ family's of ARRIA II. I did not find an information that the customer have opportunity to use on-chip (VTT) termination for HSTL-I interface standard on ARRIA GX ...

Could you give me a tip(s) if I can use on-chip termination or will be better using termination on Pcb?

Best Regards,

Roman.
