Excellent point! But spread spectrum clock modulation rates are typically about 30 kHz, so 1 ms will average over 30 cycles, which should be enough. The faster the modulation rate, the more the EMI peak is flattened. But too fast produces unaceptable cycle-to-cycle timing variations, also known as clock jitter. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
