Unlocked State Detection Timing
Unlocked state detection timing
Unlocked state detection is performed during the reference frequency (fref) period (interval). This means that a period
at least as long as the period of the reference frequency is required to recognize the locked/unlocked state. However,
applications must wait at least twice the period of the reference frequency immediately after changing the divisor (N)
before checking the locked/unlocked state.
No. 5815-17/23
LC72121, 72121M, 72121V
Figure 1 Unlocked State Detection Timing
For example, if fref is 1 kHz (a period of 1 ms) applications must wait at least 2 ms after the divisor N is changed
before performing a locked/unlocked check.
