Hello,
We use the TI Retimer IC(DS125DF111) on 10G SFP+ signal.
We have a question about DS125DF111's operation mode.
The DS125DF111 has two operation mode, one is SMBus Mode and the other one is Pin control Mode.
Could we use Pin control Mode for 10G SFP+ application( IN/OUT SFP+ trace are under 7 inch)?
Regards,
Arthur.
Hi Arthur,
For pin control mode I would recommend the DS110DF111 since the default datarates align with the typical SPF+ signaling. Since these two retimers are pin compatible no layout changes would be needed.
