PHASE LOCK LOOP (PLL) CHARACTERISTICS
Note:
1.
Measured at 50% of the input transition
2.
The maximum value for PLL enabled is given for minimum V
CO
and maximum
MF.
3.
The maximum value for PLL enabled is given for minimum VCO and maximum
DF.
4.
The indicated duty cycle is for the specified maximum frequency for which a part
is rated. The minimum clock high or low time required for correct operation,
however, remains the same at lower operating frequencies; therefore, when a lower
clock frequency is used, the signal symmetry may vary from the specified duty
cycle as long as the minimum high time and low time requirements are met.

C
PCAP
is the value of the PLL capacitor (connected between the PCAP pin and V
CCP
). The
recommended value in pF for C
PCAP
can be computed from one of the following equations:
(MF x 680)-120, for MF
≤
4, or
MF x 1100, for MF > 4.
