I would like to know which of these two (the 9952 with the comparator) and the 9958 are the quietest in terms of noise at 1kHz of the frequency?
If I compare:
-93 -90 dBc narrow band SFDR at 40MHz and 10kHz spacing
-132 -142 dBc/Hz residual phase noise at 40MHz and 1kHz, direct REFCLK
How to interpret this, when you see that the 9952 shows a much better NBSFDR on the graphs
see 9952, page 10, fig. 11
see 9958, page 12, fig. 11
Thanks for the comments.
