Divider and PLL Block
PLL Filter
MAINCK
The PLL embeds an input divider to increase the accuracy of the resulting clock signals. How-
ever, the user must respect the PLL minimum input frequency when programming the divider.
Figure 25-4
The PLL requires connection to an external second-order filter through the PLLRCA and/or PLL-
RCB pin.
Values of R, C1 and C2 to be connected to the PLLRC pin must be calculated as a function of
the PLL input frequency, the PLL output frequency and the phase margin. A trade-off has to be
found between output signal overshoot and startup time.
SLCK
Figure 25-5
shows the block diagram of the divider and PLL blocks.

shows a schematic of these filters.
