For a period of
D
So, for a period of 3 TCMs @ 20 MHz and K = 12: D
This formula is applicable for K
used. This steady value can be approximated by: D
Figure 16
Note: The bold lines indicate the minimum accumulated jitter which can be achieved by
Different frequency bands can be selected for the VCO, so the operation of the PLL can
be adjusted to a wide range of input and output frequencies:
