  Mike Neuman

  Resolved

  Part Number: LMX2581E I'm confused by 8.13.14.2 (serial microwire readback). It appears as though LD or MUXOUT are constantly being driven with readback data (regardless of LE). Is this the case? So, if I program MUXOUT_SELECT to be READBACK, the…

  Noel Fung

  Hi Peng, Looks you have a LC balan at the output and use this balun to provide the current to the buffer. I think this is not correct. The output is an open drain differential buffer. First of all, the pull-up on the + and - pin must be identical…
