I have a quick question regarding the CLKIN of the ADS131A. For our application, we have 3 devices that are using the Multiple Device Configuration Using Asynchronous Interrupt Mode shown in Figure 99 of the Sept 2016 datasheet.
Is it required that all three devices CLKIN be the same clock source?
We have been looking at various clock distribution and fan-out architectures and we are curious if each ADS131A device can be clocked from their own local oscillator/crystal?
Are there any disadvantages of doing so?
If required to be source synchronous, is it appropriate to use a standard buffer with some delay like SN74LVC3G07-EP or should a low skew buffer like CDCV304-EP be utilized?
