You can use GPIO14 to use I2S clock.

I'm trying to generate a stable frequency using internal sigma-delta clock source.
I tried different configurations but every time I occasionally get pulse slightly wider.
I'm sure that nothing in the software is interfering but I don't have a perfect frequency.

Can sigma-delta clock source provide a stable square-wave?

Thanks.
