Is my floor strong enough for 12x12 ceramic

Hi everyone and thanks in advance for your help. We want to tile our 100 sq ft (or so) kitchen -- it's on the right front half, on the second floor of our 3 story townhouse. The subfloor is 3/4" plywood on open web trusses (24" o.c.) that run side to side across the 20 foot front 2/3 of the townhouse, switching to lengthwise for the back 1/3 of the townhouse. I know that deflection can be an issue at 24" oc -- I'm hoping that I can put Ditra XL down on top of the 3/4" plywood and have enough support for the tile job. Any opinions?

And not CDX. The manufacturer says: We do not insure equivalent resistance to indention or puncture". It is a wall sheathing, not for floors, full of air pockets. Use another exterior glue plywood. Be safe, GBAR
