TMS320F280049-Q1: PLL accuracy

Wayne Huang

Dear Champs,

I am asking this for our customer.

The user needs to calculate the accuracy from a precision external crystal (20MHz) to the main clocking (100MHz) for their application for an OEM.

Do we have any spec for this part? That is, the accuracy of PLL?

Or can they assume there is almost no error here and they can assume the clocking accuracy only comes from the external crystal?

Wayne,

The PLL does not impact the accuracy. i.e. it does not degrade the accuracy of the input clock.
