Use ADF4158 with frequency below 0.5 GHz

I want to use the ADF4158 with a 100 MHz to 500 MHz  RF input frequency (RFin).

In accordance with the ADF4158 specification (please see page 3 of data sheet) a condition of the PLL at frequencies below 500 MHz is

RFin slew rate > 400V/us.

Is there an example of a simple solution to this problem   - Such as the comparator or LVPECL driver ?
