The performance of the extracted clock is characterized. The initial transient behaviour of the clock is measured when a long sequence of zero bits is present in the injected signal. The dephasing of the extracted clock due to inherent noise and the lock-up time are studied. The main goal is an estimate for the maximum tolerable zero bit sequence.
