Maximum Clock configure for FTM of S32K144

What is the maximum clock freq for FTM of s32k144?

If it uses SPLL_CLK as a External clock for clock source. 

and SPLL_CLK can be configured to 112MHz in HSRUN mode. 

Is the Maximum clock freq for FTM 28Mhz ? 

Because clock signal must not exceed 1/4 of FTM input clock which is 112Mhz in HSRUN mode.

Am I right? 

If so, Are there any ways to boost up the FTM source clock?

Hi, 

in my opinion - if you choose System Clock as clock source for FTM - the clock frequency for FTM depends on RUN mode. In HSRUN - the FTM clock is 112 MHz. Actually I didn't find any limitation related to 1/4 of system clock in Reference manual.
