AD9914 REF_CLK

Hi,

 

   I want to use a crystal oscillator w/ the PLL enabled for my ref clk and I wanted to check if my crystal would work this application. The part number

is: ASV-50.000MHZ-EJ-T. My main is conscern is that it outputs CMOS logic levels. When I used the AD9910, I used an external sine wave to drive the ref_clk so I'm unsure if this will work. Can I use a crystal with CMOS logic levels? Or there any other conscerns I need to take into account?

 

Thanks,

Caleb
