Other Parts Discussed in Thread: AM5728, , TMDSEVM572X, ADS5263, TIDA-01555
Hi,
I have the Sitara evaluation module TMDSEVM572x that contains the AM5728 and my question has to do with interfacing a high speed analog to digital converter (ADC), like the ADC3444, to this kit. Specifically, I am trying to identify a high speed ADC evaluation module that I could use for prototyping purposes and that would "hook up" to the Sitara EVM without breadboarding anything. While performing my search, I found the thread "ADC3444: ADC3444 and AM5728 interfacing through LVDS serial interface", which was asking very similar questions. My requirements at this time are that the ADC sample rate be at a minimum 10MSPS, preferably on the order of 100MSPS, 16 bit, 4-Vpp minimum (5 would be better) and I only need 2 channels. The general application is for industrial measurement solutions, not camera or video, and I'd like to get the ADC output into one of the AM5728 DSP cores. I read elsewhere that serialized LVDS is the preferred output data interface for high speed ADCs, so I am guessing that LVDS will need to be considered. However, I am very new to the Sitara EVM so I don't know if LVDS will work or at least I am not sure if there are any other options, or more importantly, what is the *best* option. In the referenced thread, it was stated that "The best ADC choice will depend on the needed sample rate and number of channels, and what interface works best with the Sitara device." Unfortunately, no follow up to that statement other than more questions appears in that thread. Since I am not yet locked into a specific ADC (that is what I am trying to determine), have I provided enough information to answer the question: What ADC EVM works best with the Sitara TMDSEVM572x EVM, subject to the ADC requirements stated above? What about an EVM-based ADS5263?
Thank you,
Nick
