Original question:

ADS8166: Initialization and data read

ADS8166: SPI-00 early data launch

Francois CRIBIER

Part Number: ADS8166

Hello,

The td_CKDO of the ADS8166 (19ns maximum) is not compatible with our master SPI that specifies a MISO Data Hold after SCK Rise of 40ns minimum.

Is there a configuration that can remove the early data launch of the ADS8166 SDO?

Thank you

Best regards

    Hello Francois,

    Unfortunately, there is no way to disable the early data launch.  If your processor is fast enough for your desired data rate, you should be able to bit-bang the interface to ensure all timing requirements are met.
