Hi Team,
My customer found DS110DF111 can't be locked with a specific SFP+ Ethernet switch (Tx).
He suspect the quality of input waveform isn't good and plan to measure the eye opening and jitter.
To measure and analysis the input waveform jitter, I believe software CDR of oscilloscope should be set to the same setting as DS110DF111 (Rx).
Could you tell me CDR mode of DS110DF111?
Is the following setting correct?
- 2nd order PLL
- 10MHz Loop BW
Best Regards,
Yaita
