Hi all,

I have a question about using SSC (Spread Spectrum Clock) in High Speed serial
design. There has been concerns that if the transceiver and the receiver use
different clocks (and both are SSC), the receiver may have difficulty to track
the bit drift due to the timing difference (which is somewhat 1 bit drift
every 200 bits for a 0.5% down-spread). Anybody has the experience or any
comment?

Thanks,

XY
