Ideal REFin type to PLL+VCO module (ADF4360-8)

What is the best REFin signal type to drive PLL+VCO module. The PLL+VCO will be used to drive RF mixers.

Should we use pure sine wave or or any square wave signals? In the datasheet and Eval board of ADF4360-8, clipped sine wave signal is used as REFin. Can we use these signals to PLL+VCO and thereby drive the Mixers ?
