Hi SI gurus, I have seen a lot of thread about decoupling capacitor, and proper = approach that should be taken for a good PDS design. One thing that is = still not clear to me is how do we calculate the peek current for = differential-pair I/O. If they are routed as differential lines, would = that number be close to zero?? Thanks, Steeve.
