Use MCO for I2S clock(SCK)

[Lixil]

Hello

I use STM32L100.

I try to use the clock output from the MCO as the I2S clock.

STM32L100 is an I2S slave and outputs an external clock using MCO(24.5MHz).

Can it use without problems？

​Thank you.

With this description and question - yes. Probably You have to ask something more specific.

AFAIK, there's no I2S in the 'L100. I don't say it can't be emulated by SPI.

Outputs the clock into what input?

Note, that PLL in STM32 introduces some jitter; this may or may not matter for your application.
