DS280DF810: Setting for 28.050Gbps data rate

Hi,

We are considering DS280DF810 for QSFP28. The data rate is 28.050Gpbs. However, we can't find the register settings for common/standard data rates. Would you please provide the 28.050Gbps settings?

Would you please provide the SNLU182 25G/28G Retimer Programmer's Guide?

Best Regards,

    Hi,

    The DS280DF810 should be able to lock to a 28.05 Gbps signal since that is within the supported lock range (20.2 to 28.4 Gbps). To configure the device to lock to this custom rate, you will need to program the device to lock to this rate.

    The DS280DF810 Programming Guide is located in MySecureSW, the same location that the full datasheet is located in. Please request access on the TI.com DS280DF810 product page under the "Special Note" section.

    Thanks,

    Michael
