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 CY29976 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

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.
