How to connect a 3.3V LVCMOS clock (single-ended) to ADCLK944 input?

I am use a 3.3V LVCMOS clock (single-ended) connect to ADCLK944 input. 

The ADCLK944 datasheet said "The input can accept dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs".

That's mean we must dc-coupled the 3.3V LVCMOS clock input, but how to connect it to ADCLK944's CLK pin? and how to connect the unused the CLK- pin? and the VT pin?

Thanks!
