The product operates down to 10MHz square wave. Preferrably witith a 100ps rise, fall time. In this case 5MHz should be present on the output. If you are using a sine wave, the minimum input frequency the device works with is 200 MHz.
For 10 MHz inputs, I usually recommend something like the AD9515 or LTC6954. They were made for slower speed inputs and have better ESD characteristics.
