Using HMC698 PLL with 10 MHz reference

I'm building a PLL using HMC698, and I have to work with a 10 MHz sine wave as reference. The phase noise of the 10 MHz is -135 at 10 Hz and -155 at 100 Hz. The HMC698 datasheet doesn't have phase noise data at 10 MHz, does anyone has data on that. Also, what is the recommended way to convert a sine to square wave while preserving the low phase noise of the input signal?
