(Different John here) Some quick and dirty residual PN measurements made on
the 100EL family versus some newer clock distribution chips from Analog
These may not be directly applicable to 100LVEL parts and shouldn't be taken
as gospel in any case, because real-world results are dependent on signal
levels and power supply contributions. But the overall trend of lower 1/f
noise than CMOS with similar broadband floors will probably hold for all of
the current-generation "fast ECL" parts. More data would be good to have.
