In many situations, a synchronization pulse is needed to ensure that the device has deterministic phase. The requirements for phase synchronization depend on certain setup conditions. In cases that the timing of the synchronization pulse is not critical, it can be done through software by toggling the INPIN_IGNORE bit. When it is timing critical, then it must be done through the pin and the setup and hold times for the OSCIN pin are critical. The following section gives categories for phase sync based on the input and output frequencies.
