The top of p. 5 of the data sheet shows phase noise for the ADCLK846 at 2 frequencies (1GHz and 200MHz).
I'm interested in the performance of the chip at 40MHz.
I'm going to be using the chip for 256QAM so I need good phase noise performance. I chose this chip because it has many buffered outputs.
I'm hoping that the phase noise specs of the ADCLK846 are as good as the rest of your clock buffer ICs (like the AD9513 and AD9517-4).
