ADC3244EVM: TSW1400EVM and ADC3244EVM startup issue

Part Number: ADC3244EVM
Other Parts Discussed in Thread: ADC3244

Hi,

We currently use 2 ADC3244 ADCs in a dual receiver architecture. We are experiencing an issue with receiver B not working during startup due to synchronization issues. Our start-up sequence is to rest all ADCs, set up each ADC via SPI commands sequentially, and then clock on to all ADCs simultaneously. Can you assist us in identifying the problem by providing us with the source code ADCs for TWS1400 so that we can compare the code?

Hi Duong,

A few questions first.

What source code? The FW to the TSW1400? You made some modifications? If we gave you our FW code in the past, unfortunately, we cannot support modifications.

Also, it would be helpful if you provided a block diagram of your test setup so we know exactly what you are trying to do here.

Regards,

Rob

We are using Xilinx FPGA to interface multiple ADC3244 in the design for a dual receiver. We are experiencing an issue with receiver B not working during startup due to synchronization issues. We were wondering if TI can provide the source code for the FPGA ADC interface in TSW1400 so that we can compare our code with yours to resolve the issue.
