Crosstalk on PCB Thanks Joel B and jippie. I agree, I changed the resistance of the stub and observed how the signal reflections change. My best option would be to use the shortest possible pogo pin with very low capacitance and inductance. |

Crosstalk on PCB Thanks for the reply jippie. The clock runs at 400MHz. I did some more experiments and now see some ground noise everytime I add the stub. The rise time increases with addition of the stub. Obviously, ground noise is feeding back in to DQS. Question is why would adding a pin or a stub on clock line cause ground bounce so badly. |
