Hi everyone,
I looking for some clarification as to the possibility of a damaged board or if its within specs:
My 7010 SOC is attached to the Microzed FMC MBCC carrier card. Bank 34 and 35 is supplied with VADJ that is jumpered to 1.8V.
Without the SOC or anything attached to the carrier, the test point for VADJ (jumpered for 1V8) measures 1.802V - which is correct.
However, once I plug in the SOC, it measures to be approximately 2.3-5V. The other test points (5V0 and 3V3, MAX15066) measure correctly.
This happens also for our other 7010 and 7020 boards + MBCC - from stock.
My question is the following (above note is for reference in case its relevant):
For my ADC, it sends out a differential signal biased at 2.5V into the inputs of the 7010 SOC (Vmax amplitude is 2.9V). this would mean the highest signal amplitude that
goes into Bank 35 would be 2.9V (well below the 7010 HR bank max of 3.6V). However, since I've set Bank 34 and Bank 35 to be 1.8V (from the jumper on VADJ), is it possible that by sending in a signal above 1.8V into Bank 34/35, I've damaged the SOC? Even though the Xilinx DS187, states a max HR for VCCO of 3.465V?
Thank you.
Regards,
Ron.
