DS125DF111: DS125DF111

Part Number: DS125DF111
Other Parts Discussed in Thread: DS110DF111

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.

    Regards,
