is more important that the noise on the Low power clock line remains substantially below the hysteresis in amplitude.
perfect frequency. Due to this, the total jitter value must contain the jitter itself and the error due to the accuracy on the
clock frequency. The lower the accuracy, the smaller the jitter is allowed to be.
