The D90203DJC IEEE 802.3dj Tx test application simplifies complex 212 Gbps IEEE transmitter physical layer measurements to help you:

  • Reduce time spent understanding the details of standards.
  • Decrease the time it takes to characterize your PAM4 design from hours to minutes.
  • Enable the debugging of your device using custom configurations.
  • Generate HTML reports that summarize the performance of your device quickly.

Key measurements include:

  • Jitter measurements Jnu, JRMS, and EOJ on a 12-edge PRBS13Q.
  • Output waveform measurements, including steady-state voltage, linear fit pulse ratio, and signal-to-noise-and-distortion ratio (SNDR).
  • Effective return loss.

D90203DJC IEEE P802.3dj Measurement and Conformance Application Software

The D90203DJC solution is an Infiniium UXR Series Oscilloscope based electrical validation software application which performs IEEE P802.3dj 212Gbps physical layer electrical validation for C2M (Clause 176D) and CR (Annex 179A). C2C (Annex 176C) and KR (Clause 178) support will follow as these sections are advanced in the draft P802.3dj specification. This semi-automated test solution will support unform application of the accepted measurement science and methods established by the IEEE P802.3dj technical task force’s draft specifications. Test limits and methodology are all subject to change before the final IEEE standards release which is expected in Q4 2025.
