If that subfloor is T&G style, you could install a nominal half-inch exterior glue plywood second layer and tile directly to that. Presuming both layers were correctly, and differently, installed. As pointed out above, we (TYW) generally do not recommend that method, but it is a published method in the TCNA Handbook (F150).

But that makes a good subfloor and you could also install any tile substrate product you want over that. There are many such, ranging in thickness from less than 1/16th-inch to 1/2-inch.

My opinion; worth price charged.
