Create external signal with clock 100 Mhz in STM32H745

[Ronil]

Hi all, I have already searched on the forms and in general did not find an answer to my problem, I will be very grateful to you for help.
I need to create an output signal with a frequency of 100 Mhz as CLK in  STM32H745. I used the Discovery Boards (STM32H745I-DISCO STM32H750B-DK) for the test. 

1. I used timers with PWM and adjusted the ABM timer clock for 220 MHz, set up pre-scaler and counter period

 

But I achieve only 50 Mhz a clock as a maximum, with settings for 100 Mhz there is nothing at the output for CLK. To detect the clock I use PicOscope6404D (Bandwidth 500 Mhz).

2. I used as output ch A8 and adjusted A8 for  RCC_MCO_1

I used the next settings but received the same result as for Timers not more than 50 MHz. Can you explain why I have this limitation (because the device settings show me that I can reach 100 Mhz but in real not )?

3. Finally I used the PA8  HRTIM_CHB2 timer and received high and very unstable frequency with very low amplitude. Do you how I can make a stable frequency and increase amplitude from HRTIM_CHB2?

[BarryWhit]

I'm not sure anything except dividing the internal clock and outputting it via the dedicated RCC MCO pin is a good idea, 100Mhz for GPIO pins seems unrealistic.

Try setting the GPIO drive strength higher via the GPIOx_OSPEEDR registers. Let us know if it works or not.

[MasterT]

Should work, I have H743 running spi at 120 MHz SCLK. 

Try osciloscope probe with 1:10 divider to minimize capacitance.

[Ronil]

Hello, thank you, what do you menas should work? timers, RCO,  GPIOx_OSPEEDR registers or just SPI protocol?

[Ronil]

Thank you, I will try, I just was wondering if STM Cube showed me that is possible in fact doesnt work 

[MasterT]

I mean GPIO needs  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;

For RCO there is no GPIO stettings , publish your code so we can see if it's really configured, for ex.:

 HAL_RCC_MCOConfig(RCC_MCO2, RCC_MCO2SOURCE_SYSCLK, RCC_MCODIV_10); 

Same apply for Timer. print code.

If you don't know capacitance of oscilloscope probe, use a buffer kind of "active probe"

[SofLit]

Hello @Ronil ,

I kindly requested an internal colleague to do the test on a Nucleo H753 with KEYSIGHT DSO9254A oscilloscope. 100MHz is output on the MCO pin like shown in this oscillo screenshot:

So you need to use an adequate oscilloscope and probes for these high frequencies.

[Ronil]

Thank you for your message it is a code that doesn't operate for general timers T13 and T15 and for HRTIM, I used many different options for pre-scaler and counter period. But didn't achieve more than 50 Mhz for T13 and T15 and from HRTIM I didn't receive a stable signal

thank you so much, I use PiScope which operates until 500 Mhz, can you watch my script I expect receive 96 Mhz, but  is nothing

Probably I solved the problem! thank you all!
