Posting for a customer:
I am currently using the CDCE949 Clock generator chip to run various clocks for our ADCs and DACs. However, we are running into a small issue that I really don't know how to explain.
We are using a Crystal oscillator running at 25MHz to generate various clocks across the board.
Here are their frequencies
- y0= 192k
- y1= 192k
- y2= 192k
- y3= 12.288M
- y4= 12.288M
- y5= 12.288M
- y6= 12.288M
- y7= 12.288M
- y8= 0
- y9= 24.576M
When I use an oscilloscope on the 192k signals and 12.288M, I get this strange strafing between the two signals. attached is a video showing exactly what I am witnessing. I have also gotten this same error using a TCXO that is 25MHz. Let me know what your initial thoughts are on this. Hope to hear back from you soon!
