Hi,
We have integrated the DS250 Retimer with the LX2160 NXP Network Processor in one our design. We wanted to configure and test the Retimer for 10G.
Please let us know how to configure and test the said Retimer to 10G.
Thanks & Regards

Hi,
Please confirm the exact 10G rate you are using (e.g. 10.3125Gbps) and whether you are using CAL_CLK_IN = 25MHz.
Thanks,

In that case, please refer to the table below taken from retimer programming guide with values for the relevant channel registers to configure CDR for 10.3125Gbps.
