Hi,

What is the requirement of TPS68470 regarding the accuracy of XTAL connected to OSC_IN/OSC_OUT?

And what is accuracy requirement from HCLK_A/B usually?

Thanks!

    Hi Antony,

    The crystals recommended in section 9.2.2.5 of  the datasheet all have an accuracy of about 30ppm, so that is a good starting point.

    I am bringing this to the attention of the experts for this part, and they should be able to give you a more complete answer. They are on holiday for Thanksgiving, and should be available early next week.

    Thanks,
