MC56F84789VLL maximum sys_clk_2x signal frequency

Contributor I

Dear all,


On the reference manual MC56F847XXRM Rev. 2.0, 03/2016, I noticed that the max frequency of sys_clk_2x should not be more than 200MHz, as shown in figure 18-3, page 352.

Is it a maximum absolute rating? I didn't find any other specifications about it.

What would happen if this frequency was exceeded?

My company has several items working with sys_clk_2x equal to 204,8MHz (that produces accurate baudrates on QSCI). Would it be dangerous for the DSP itself in terms of stability, reliability or anything else?


Best regards,

Federico Gobetti.
