TLV2541: STM32 interfacing

Long Le
Prodigy 60 points
Part Number: TLV2541
Other Parts Discussed in Thread: ADS5295

Tool/software:

Hi TI supporter,

I'm finding the high sampling rate ADC ( >=100Msps) 12 bits can interface with STM32.
I found the SPI ADC but it can not approach to 100Msps. The 100Msps or higher is using the LVDS/ CMOS method and I dont know how to interface with my STM.

Please give your advice.

Thank you,
Long Le

    Hi Long,

    SPI interfaces just cannot maintain the digital signal integrity at those high speeds, so you won't see any ADCs at or beyond 100MSPS with a SPI interface. I don't suspect the STM32 can supply a clock fast enough to your ADC for you to be able to achieve those sampling rates either. Can you repost this question with the ADS5295 part number, so that a member of the high-speed ADC team can take a look at this and help you with your requirements? The TLV2541 device you posted this under only goes up to 200kSPS.

    Regards,
    Joel
