Clock State
The current state of the recovered clock.
The possible states are (read-only):
•
Free run – the clock recovery is not
locked/attached to any PSN clock source.
The internal oscillator generates the clock.
•
Frequency acquisition – the adaptive clock
recovery process is currently attaining the
clock frequency.
•
Rapid phase lock – the clock recovery is in
learning process until it reaches fine
phase lock state.
•
Fine phase lock – the unit is locked on the
PSN clock source. The recovery is stable
and received at the required quality level.
