iMx6 DDR3 VTT

[yannickc]

Dear All,

On SABRE evaluation boards and many others, no VTT is supplied to DDR address bus. Is it useless to add VTT on DDR with iMx6 ?

On TWR-VF65GS10 board with a Vybrid VF65GS10CMK40, a VTT is used on DDR3.

Best regards,

Yannick

Yannick,

we placed termination resistors: just in case. At the end they are not necessary: so we don't assembly them. Since we don't have a good simulation tool, we decided don't take risks.

Regards,

Manuel.
