In this context, SSC means Spread Spectrum Clocking.

It's a technique to slightly adjust a clock frequency over time to avoid EMI (electromagnetic interference) issues at certain frequencies.

Subject: SAS-2 SSC Investigation - Is this Tape?

Barry,

I am confused here. First, in SCSI SSC refers to SCSI Stream Commands. I see no mention of tape in this proposal. From what I read it appears that SSC is referring to some kind of filter or like method of signal modification. Would you please provide the meaning of this acronym in your document? Also, if possible could you find an acronym to use that does not confuse us that are unable to attend SAS WG meetings?
