Hello,
To continue my work with the timers, I am going to work with a clock of 150MHz for them. Is there any influences on the serial port if I use this clock? I work on a Teensy 4.0. The documentation is complete but so difficult to manage, especially for a non english natural language.
Thanks
Michel
 
Paul already answered this, but thought I would mention that when you are wondering about the options for configuring the clocks associated with different sub-systems.

I will often look at the CCM Clock Tree (Section 14.4) in the IMXRT1060RM pdf file.
Page 1016 on near to the top right shows the output timer for PIT, GPT and as you work your way back to the left you can see what clocks are fed in and different options.
Register names and the field within the register. These registers are described later in the CCM chapter.

The LPUART output is on the next page. In both cases we initialize to using the 24mhz clock(OSC).
