When designing high speed serial channels such as PCIe Gen2 5 GBPS and SATA
III 6 GBPS what frequency components are of interest? Do you only consider
the fundamental (2.5 and 3.0 GHZ) or does the third harmonic also need to
be present for good signal integrity? Most the parts I look at have have a
few db loss at the fundamental but significant loss at the third harmonic.
Thanks - Joel
