Hi,
I have an inquiry about PLL Accuracy of CYT2B9.
I am trying to supply the multiplied frequency through ECO and PLL to use CANFD.
What is the accuracy range of the PLL?
Is it the same as the ppm of ECO XTAL?
In the case of FLL, as shown in the attached datasheet, an error of ±1% is added to the source clock.

Thanks and Regards,

Hello @YongseokJeon 

  1. There is no specific accuracy range mentioned for PLL.
  2. The PLL accuracy mainly depends upon the Long-Term jitter.
  3. Please refer the below screenshot which is taken from the datasheet itself which states about the jitter values for PLLScreenshot 2023-07-19 101822.jpg

Thanks & Regards
