MPC9992
APPLICATIONS INFORMATION
SYNC Output Description
The MPC9992 has a system synchronization pulse output
QSYNC. In configurations with the output frequency
relationships are not integer multiples of each other QSYNC
provides a signal for system synchronization purposes. The
MPC9992 monitors the relationship between the A bank and
the B bank of outputs. The QSYNC output is asserted (logic
high) one QA period in duration. The placement of the pulse
is dependent on the QA and QB output frequencies ratio.
Figure 3 shows the waveforms for the QSYNC output. The
QSYNC output is defined for all possible combinations of the
bank A and bank B outputs.
