Actually I have some AD9851 DDS ICs in my circuit like the below:
so I need a CMOS clock distributor to feed them simultaneously.
the supply voltage for AD9851 is +5V bcoz in this condition the maximum output frequency can be achieved as following:
as you see in the above the the minimum level to have logic 1 is 3.5V. the problem it is.
is there such clock distributor for such application? ADCLK846 is a good choice? I think I should place a resistive network to meet the required condition.
my friends used this circuit to use some AD9851: (I think it's not a good design bcoz we should isolate the clocks)
