800MHz counter on Cyclone ?

I need a high resolution (28 bits or more) with an 800MHz clock. Is it possible to use the VCO to clock a counter if I run the PLL with a M=8 multiplier with a 100Mhz to get a VCO of 800MHz ?

OK, I think I've got a working solution using all 5 of the PLL outputs each with a unique phase. Now onto figuring out how to implement the interpolator.
