Z9973
SYNC Output
In situations were output frequency relationships are not integer multiples of each other the SYNC output provides a
signal for system synchronization. The Z9973 monitors the relationship between the QA and the QC output clocks. It
provides a low going pulse, one period in duration, one period prior to the coincident rising edges of the QA and QC
outputs. The duration and the placement of the pulse depend on the higher of the QA and QC output frequencies. The
following timing diagram illustrates various waveforms for the SYNC output. Note that the SYNC output is defined for all
possible combinations of the QA and QC outputs even though under some relationships the lower frequency clock could
be used as a synchronizing signal.
