(Different John here) Some quick and dirty residual PN measurements made on
the 100EL family versus some newer clock distribution chips from Analog
Devices:

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.
