Part Number: LM15851EVM
Hi!
The LM15851 datasheet states that each NCO_x pair must be connected together and driven with a common 1.8V LVCMOS signal (but, as it's seen in the Pin Functions table, these inputs appear to have differential structure). In turn, in the LM15851EVM a single-ended connection to only one side of these differential inputs is made. A differential connection to these NCO_x inputs is made as well (exactly as it's made for DSx outputs). It's a bit confusing.
Can you give some explanations on why you connected to the NCO_x inputs in such a way? Why didn't you do it as the datasheet requires?
Thanks in advance.
Regards, Vic.
