Hi All,
In one of my projects, I am using 2 Clock Synthesizer ICs - CDCE62005 to generate 10 frequencies on board, with 5 frequencies generated from individual clock synthesizers.
Now, using the SYNC pin in CDCE62005, I have managed to synchronize 5 individual output clock frequencies of each CDCE62005 with respect to each other (i.e. there is no phase shift between them and their rising edges are also aligned)
However, the clock outputs of the 2 CDCE62005 ICs dont seem to be getting synchronized with each other. Their rising edges seem shifted (clocks seem phase shifted) although the source from which CDCE62005 ICs are generating their respective clocks are the same. I presumed that since the source is same, generating the SYNC pulse for individual Clock synthesizers should automatically synchronize their clocks with each other.
Since this does not seem to be the case, is there any other method by which I can synchronize the output clocks of the 2 clock synthesizer ICs? Or do I need to "adjust" the clocks by inserting appropriate phase shifts through the register settings of CDCE62005?
Hoping for a positive reply at the earliest. Any sort of guidance/suggestions will be appreciated.
Thanks in advance.
Regards,
Sid
