MSPM0G3107: SYSPLL

Kenley

Part Number: MSPM0G3107

Tool/software:

Hi team,

The accuracy of SYSPLL is not described in the datasheet.

Does the accuracy of SYSPLL depend on the accuracy of SYSOSC?

Please let us know how much accuracy improves/worsens by passing through SYSPLL.

Best regards,

Kenley

Hi, Kenley

For the accuracy of SYSPLL, it is influenced by clock source, SYSOSC or HFXT.

And we have SYSPLL jitter spec in datasheet https://www.ti.com/lit/gpn/mspm0g3107 :

7.9.3 System Phase Lock Loop (SYSPLL)

JitterSYSPLL SYSPLL RMS cycle-to-cycle jitter fSYSPLLREF=32MHz, fVCO=160MHz 24 ps
