Hello,

sorry for maybe stupid question, but I can't understand - how to make the frequency divider using STM32F4's timers?

I mean how to divede the frequency of the external signal and output it from CPU?

Tnanks.

No, no, I do not need a frequency generation - I have external clock from D/A converter, and want to syncronize MCU's I2S output with it. This frequency is ~37MHz but I2S requires 49MHz.

I have frequency multiplier, and I think to make (37/3)*4

P.S. PLD is considered.
