PLL lock problem.

Question

I am experiencing calibration time durations from 10s of milliseconds to seconds. It seems to be due to the PLL lock times. I am running the PLLs at either 960 MHz or 921.6 MHz. Observing the RX PLL lock bit (0x247-bit1) and TX PLL lock bit (0x287-bit1), both stay low after calibration. 
 How to calibrate with PLLs locking in a few milliseconds?

Are you operating under normal temperatures? Have you tried initializing with the default initialization settings in the driver?)
