Part Number: DS280DF810

Hi

I find the description of DS280DF810  as "Including Sub-Rates Like 10.3125 Gbps, 12.5 Gbps, and More".

Does it also can support 16GFC (14.025G)? If yes, which register or setting I should modify?

Thanks

    Hi,

    The DS280DF810 retimer part number does indeed support 14.025Gbps rate in retimed mode. The user can program the retimer channel(s) in question to this rate via the SMBus channel registers settings below:

    Addr       Value     Comment

    0x60       0x20       14.025G rate (28.05G)

    0x61       0x46       14.025G rate (28.05G)

    0x62       0x20       14.025G rate (28.05G)

    0x63       0x46       14.025G rate (28.05G)

    0x64       0xFF       Max PPM tolerance

    0x18       0x10       Set to divide by 2

    0x09       0x04       Enable divider select override

    Cordially,
