PRODUCTION DATA
The APLL XO doubler can be enabled to double the PFD frequency for the APLL reference. 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.
