Other Parts Discussed in Thread: ADC12DL3200,
I am trying to configure a new high speed data capture EVM (fresh from the sealed ESD bag) to use with the ADC12DL3200, but the board will not power on. I followed the few steps outlined in the data capture user guide, and cross-checked against the setup procedure described in the ADC user guide for consistency. I attached the TSW14DL3200EVM and the ADC EVM, then connected the provided power cables to a 12v supply (5v for the ADC) capable of delivering more than 3 A (recently calibrated), and verified the voltages with a multimeter (outer surface at ground, inner surface at V+). I then plugged the TSW14DL3200EVM into my computer with the mini USB 3.0 (the ADC and TSW manuals differ here. One says to plug in the USB after turning on power, the other says to do it before...probably doesn't make a difference, but it's worth noting), and enabled the output of the 12v supply. At this point LED D19 did not light, switching SW2 to the on position did not activate any of the status lights, and my computer did not recognize any new USB 3.0 devices. I verified that 12v was present between TP18 and TP19, so I don't think there's an issue with the power supply. I checked the voltage across LED D19, and found that it was only at ~1v, which is probably not enough for it to light (assuming it's a green LED). Maybe this means there's a problem with the power conditioning circuit?
I did all this work while wearing a wrist strap at a grounded ESD station with fault monitoring, so I don't think there's a chance of accidental electrostatic damage.
I'd appreciate any advice or suggestions for further diagnostics. We have a near term need for this board, so I'm hoping we don't have to submit an RMA.
