Clock for AD7705BRZ from Microcontroller (STM32F100C4)

Hello!

I have some difficulties with my circuit developing. I don't have any crystall resonantor on my PCB but AD7705 need to be clocked externally. I've decided to use clock output from microcontroller (STM32F100). But I don't shure. Can you look at my scheme?

Thanks #ad7705 #stm32f100

Just connect MCLKIN with the clock you're outputting via PA8

Do NOT connect MCLKOUT, and don't connected that back into the OSC IN/OUT of the STM32, it's pointless.Connect the RESET for the AD7705BRZ to a GPIO pin on the STM32 you can control it, as PA8 isn't going to be generating a clock when you would normally start the system.
