The APLL XO doubler can be enabled to double the PFD frequency up to 50 MHz for APLL1 and up to 150 MHz for APLL2 in Non-Cascaded mode. Enabling the XO doubler adds minimal noise and can be useful to increase the PFD frequency to optimize phase noise, jitter, and fractional spurs. The flat portion of the APLL phase noise can improve when the PFD frequency is increased.
