Async Clock Signal

I'm making an interface that requires a clock signal output that is 16x the UART baud rate (9600) which puts me at 153.6 kHz.
I was trying to generate this on the clock out pin but it doesn't seem mathematically possible. 
What other options do i have besides just hitting a gpio port?


This is on a MKE18F

Hi

A Flex Timer may be possible if you have a source that it can use to derive the exact frequency.

Is there any option that doesnt require adding an additional source?

I dont want to add any more components to the board.

I am running the external 8mhz clock but that's it.

The FTM can be clocked from various sources:

If you can generate 9600 Baud on the LPUART (with the same clock sources) a x16 clock will also be possible with the same resolution.
