PRODUCTION DATA.
When the internal LO is used, IF outputs of two devices can be synchronized to the Fosc input if and only if the VCO frequency is a multiple of the Fosc frequency and there is no multiplication in the input path (OSC_2X = 0 and MULT=1). The device is inherently in SYNC all the time in this condition so therefore there is no need to use the SYNC pin or to toggle the SYNC_PHASE_PLL bit.
