Part of the device initialization aligns the rising edge of the output clock to the internal 1 PPS clock. If the system APLL and DPLL is not locked, then the alignment will fail and there will be a fixed offset between the internal 1 PPS clock and the output clock. After loading the device firmware, poll the system APLL and DPLL for locked state prior to initialization, timing out after 2 seconds.
