Which modes must be used in order to maintain synthesizer phase during RX/TX/Standby switching?

 

Conditions:

-All chips are fed with a common ref clock (40MHz)

-There is a calibration system which is used to find the phase relation between all the chips for both RX and TX.

-Calibration is performed after power-up and every time the frequency is altered.
