voltage of the output clock signals when they are used as CMOS single-ended. I
would need a clock signal ranging from 0V to 3.3V, can this signal distributed
in the AD9508 getting the same range of voltage in the outputs?
The CMOS output levels are typically 0 to 1.8V for no load. The data sheet has
the specifications on how that amplitude changes with different load currents
as given below-
The AD9508 does not support 0 to 3.3V CMOS drivers, only 1.8V.
