DP83TG720S-Q1: 1000Base-TI psd fail

Part Number: DP83TG720S-Q1


  • During ​PMA​ ​PSD​ testing, it was observed that the curve starts slightly lower (−83 dBm/Hz).

  • ICs​ from different ​batches​ exhibit inconsistent performance when populated on the same ​PCB.

  • Shorter traces perform better than longer ones; the marginal case fails at around ​400 MHz.image.png
