5.2
This section lists and describes the signals that connect off chip.
5.2.1
These pins provides operating voltage (V
the supply voltage to the PLL to be independently bypassed. Even if PLL usage is not required V
and V
5.2.2
A passive external loop filter must be placed on the XFC pin. The filter is a second-order, low-pass filter
to eliminate the VCO input ripple. The value of the external filter network and the reference frequency
determines the speed of the corrections and the stability of the PLL. Refer to the device overview chapter
for calculation of PLL loop filter (XFC) components. If PLL usage is not required the XFC pin must be
tied to V
