AD9575 input - crystal only or LVCMOS compatible?

Product Number: AD9575

Software Version: NA

Is the AD9575 input - exclusively setup for a crystal only or can it be driven with an LVCMOS signal?

If it can then I assume it would be driven into XO1, XO2 left open/Grounded?

Thank you.

Hi,

the AD9575 can only have a crystal resonator connected at the XO1, XO2 pins. It cannot receive a CMOS clock at one of these pins.

Please take a look at the AD9552 or the AD9553 for chips that can receive a reference clock and create two output clocks.
