to lock (tracking mode) to a reference. If
the LED flashes continuously over an
extended period of time, check the CC
STAT in LD 60. If the CC is tracking this
may be an acceptable state. Check for
slips and related clock controller error
conditions. If none exist, then this state
is acceptable, and the flashing is
identifying jitter on the reference.
