DS125DF111: retimer p/n pin swapping

rick Yu

Part Number: DS125DF111

Dear colleagues,

We use DS125DF111 to repeat a 10G SFI signal.
To facilitate PCB layout, I intend to swap the polarity on both sides of the device, is this acceptable?

Thanks in advance!

Hi Rick,

Yes, this connection is okay. The output polarity can be inverted by writing 0x1F[7] = 1'b1 after selecting the channel.

Thank you,

Evan

Hi Evan,

Thanks for your prompt reply.

Just confirm again; if only one side is swapped, then I need to change 0x1F=1'b1 for that channel, right?

Hi Rick,

That is correct (0x1F[7] = 1'b1).

Thank you,

Evan
