ADF4002 minimum RF input frequency

actually i'm looking for a stand alone PDF and charge pump to use inside a prototype of triple loop PLL architecture. During my search i have found the ADF4002, but i have a question on its minimum value of RF Input frequency. I would try to use the component with an input frequency on the RFin port of 500KHz. The datasheet report that "For RFIN < 5 MHz, ensure slew rate (SR) > 4 V/µs" on the RFin input port, but the graph inside the same datasheet report the sensitivity on the same port only for frequencies up to 1MHz. So this is my question: is possible to made the component work for a frequency of 500KHz on RFin port ?
