Hello,
DP83848K TXD waveform is measured as attached. The high frequency noise on the signal is observed.
This high frequency noise can observe in 10Mbps case. 100Mbps case is no issue.
[Question]
1) What is the thinkable reason we can observe the noise on signal? I think we can see clean signal if EVM is used.
2) Would you share me DP83848K EVM TXD waveform of 10Mbps for the reference? We want to confirm what signal is proper signal quality.
Best regards,
Toshihiro Watanabe
