Dear community,
We have been developing our product with iMX7D.
I have a question about ECSPIx_CLK_ROOT jitter.
In Data sheet IMX7DCEC Rev. 2, 4.4 PLL electrical characteristics,
it is not described the PLL jitter specification.
[Question]
Please tell me the PLL jitter specification.
Best Regards,
Koichi Sakagami

Hi Koichi
1. ECSPIx_CLK_ROOT jitter is not much affected by PLLs jitter, as
PLLs jitter is averaged on many PLLs cycles, since ECSPI clock is less
frequency than PLL.
2. ECSPIx_CLK_ROOT and PLLs jitter are not specified by datasheet,
if you have special reasons for obtaining it, please escalate your
requirements through local fae channel.
Best regards
igor
