Hi Jiawei,
I recommend CDCE6214 instead.

See provided TICSpro config for reference.

24Mhz input 302.95Mhz outputs CDCE62124.tcs

Hi Vicente,

Thanks for your reply!

Input is crystal
2 outputs of 302.95MHz LVCMOS clock
Supply voltage doesn't matter

Could you kindly share a part number and tell me how to configure?

Hi Jiawei,
Is a LVCMOS input a must or as is any single ended input fine? Current consumption will be too high above 250Mhz. Duty cycle and amplitude will both suffer. Potential for EMI problems as well.

Here are some alternatives.
