Hi everyone,
I am an electronic engineering student and for my bachelor's thesis I want to design a USB3.0 oscilloscope with the highest possible speed and signal measurement frequency range. I would like to use an STM32H7 MCU with a 16-Bit, 160Msps ADC LTC2209, but it only has LVDS or CMOS outputs. Is it possible to combine this ADC with STM32? Perhaps the SN65LVDS32 interface would be suitable?
Also, since the STM32 would not be able to process the data at this speed, would a buffer not degrade the final parameters? Perhaps a lower sampling rate ADC would be worthwhile. It would be interesting to know your opinion.

 

This is doable and I have already done it with different components. I have used STM32F407. STM32H7 were not yet available at the time I did this. You don't need any additional interface. You don't need a buffer. STM32 MCUs can interface directly with high speed ADCs running at max sampling rate.

I would not even go with USB. I would use a touch screen LCD-TFT. With TouchGFX you can create a beautiful colour handheld oscilloscope.
