SYNC Output Description
The MPC9773 has a system synchronization pulse output
QSYNC. In configurations for which the output frequency
relationships are not integer multiples of each other, QSYNC
provides a signal for system synchronization purposes. The
MPC9773 monitors the relationship between the A bank and
the B bank of outputs. The QSYNC output is asserted (logic
low) one period in duration and one period prior to the
coincident rising edges of the QA and QC outputs. The
duration and the placement of the pulse is dependent on QA
and QC output frequencies: the QSYNC pulse width is equal
to the period of the higher of the QA and QC output
frequencies. Figure 6 shows various waveforms for the
QSYNC output. The QSYNC output is defined for all possible
combinations of the bank A and bank C outputs.
