Other Parts Discussed in Thread: DAC38J84, DAC38RF89EVM, DAC38RF89
After we received our new TSW14J57EVM, we connected it to our DAC38J84 and powered them up. I noticed that only a few of the power rail indicator LEDs were lit. I probed the different supplies of the board, and found that the VCCIO_1.8V switching supply had its enable asserted high (PSEN3), but the output was zero. After depowering the board, I used a DMM to measure the resistance to ground for the different power rails and determined that VCCIO_1.8V appeared as a hard short. All of the other rails did not.
I presume that I will need a replacement board.
