I am attempting to bring up the AD9364 using the no-os drivers. I have modified the initialization routine to use a 10MHz external oscillator. Nothing else has been changed. The calibration routines are completing and the BBPLL is locking however, both the RX and TX RF PLLs are not locking. Registers 0x247 and 0x287 both return 0x0. Is there anything else that I need to do to get the PLLs to lock?
