IMXRT1064 LVDS CLK input usage

[dbasilio83]

Hello

Our query relates to the LVDS 'CCM_CLK1_P/CCM_CLK1_N' external clock input on the IMXRT1064. It states in the datasheet:

"One general purpose differential high speed clock Input/output (LVDS I/O) is provided. It can be used:
• To feed external reference clock to the PLLs and further to the modules inside SoC."

We would like to run the timer modules (GPT, TMR) on the IMXRT1064 off this external 100MHz LVDS clock, but run the ARM core clock off 600MHz that is generated from the external 24MHz crystal.

Our question is:

1. Can one run the ARM core clock (AHB_CLK) unsynchronized from the peripheral bus clock (IPG_CLK) ? 

Thank you in advance
