9.7.4.3.1 Normal Mode
9.7.4.3.2 Mode 1a: Normal operating mode without post-divider and without pre-divider
9.7.4.3 Use of PLL0 operating modes
smaller than the so called “lock criterion” for more than seven consecutive input clock
periods, the lock output switches from low to high. A single too large phase difference
immediately resets the counter and causes the lock signal to drop (if it was high).
Requiring seven phase measurements in a row to be below a certain figure ensures that
the lock detector will not indicate lock until both the phase and frequency of the input and
feedback clocks are very well aligned. This effectively prevents false lock indications, and
thus ensures a glitch free lock signal.
To avoid frequency hang-up the PLL contains a frequency limiter. This feature is built in to
prevent the CCO from running too fast, this can occur if e.g. a wrong feedback-divider (M)
ratio is applied to the PLL.
Table 72.
Mode 1 is the normal operating mode.
The pre- and post-divider can be selected to give:
To get at the output of the PLL (clkout) the best phase-noise and jitter performance, the
highest possible reference clock (clkref) at the PFD has to be used. Therefore mode 1a
and 1b are recommended, when it is possible to make the right output frequency without
pre-divider.
By using the post-divider the clock at the output of the PLL (clkout) the divider ratio is
always even because the divide-by-2 divider after the post-divider.
Table 73.
In normal operating mode 1a the post-divider and pre-divider are bypassed. The operating
frequencies are:
