HMC833LPGE input divider reset

For our application we need output signals (at difference frequencies) with a stable phase w.r.t. the reference signal. However, when the HMC833LPGE is used in integer mode, there is jumps in the output phase. It seems to be due to the input divider being reset during an frequency change (the jump in phase corresponds to the division ratio R). If the autocal functions is switched off, no such jumps occur. Is it possible to set the HMC833LPGE up so that the input divider (/R) is not reset during autocal?
