NOTES:

1. Time from reappearance of a valid signal at RPOS and RNEG to a LOCK=1.

2. Minimum peak voltage necessary for proper processing of signal.

3. Loop bandwidth when in lock (LOCK=1).

4. When out of lock (LOCK=0), measured as a percent of incoming clock frequency.

5. Maximum input jitter in unit intervals at 10 Hz.
