    DDR3 hardware circuit design

    Hi Friends,

    currently i am designing an 64 bit DDR3 with fly by topology. for address and command i have 47ohm far end termination. do we need any termination for clock pairs. also if you have any specific hardware guidelines please let me know other than layout guidelines.

    Thanks
