ADC34J44EVM: Coherently clocking multiple boards

Hi Aravind,

Synchronizing and capturing data from multiple ADC34J44s is possible, but I am not certain if we have the firmware available to support this on the EVM. At a first glance, I would assume two capture cards are needed that would need to be triggered simultaneously. You will need to have a synchronized clock source for both EVMs as well (length matched cables).

I will investigate further into the firmware, and get back with you shortly.

Best Regards,

Dan

Hi Aravind,

I have found a path forward for the 8 channel capture that you have requested, but we will need to do some firmware work on our end.

Here is a list of items that you will need:

(2) ADC34J44EVMs

(2) TSW14J56EVMs (two +5V power supplies, at least 4A each)

(2) Synchronized clock sources for sample clock (with length matched SMA cables). You might be able to use a splitter here if your source has adequate output power.

(2) SMA cables (length matched) for triggering TSW14J56EVMs data capture.

Let me know once you have these items, and I can move forward with getting the procedure working/documented.

Best Regards,

Dan
