imx8m mini output of Mipi_ CLK signal is not very stable like below,is it normal?
other CPU output MIPI_CLK is stable , like below:
How to optimize and let imx8m Mini output stable signal?
Hi Darcy
for stable signal it is necessary to check mipi layout described in sect.3.5. Trace impedance recommendations, sect.3.4.7. High-speed routing recommendations
i.MX 8M Mini Hardware Developer’s Guide
Also pay attention to attached mipi cables and connectors, they also should have proper
impedance matching.
Best regards
