The docs are over here http://www.linuxcnc.org/docs/2.5/html/drivers/hostmot2.html they say "The encoder sample clock runs at 33 MHz on the PCI Anything I/O cards and 50 MHz on the 7i43." without the filtering-mode "the quadrature counter needs only 3 clocks to register a change" So a change can be recorded at 33MHz/3 = 11MHz, and there are two changes in one cycle, so in theory the max count-rate would be 5 MHz.
