DS150DF1610: For 6.6Gbps

Part Number: DS150DF1610

Hi,

Our customer is looking for 6.6Gbps Retimer. Does the DS150DF1610 support 6.6Gbps? If so, could you provide the register settings for the data rate?

Best Regards,

Kato

    Hi Kato-san,

    Yes, the DS150DF1610 can support 6.6 Gbps. To do this, you will need to change the VCO frequency to be 13.2 GHz and then change the divide-by counter to include the ability to lock to "divide-by-2" so that the VCO is able to lock to 6.6 Gbps.

    To configure, follow the steps in Section 8.3.2 for manually programming the Data Rate Selection.

    I suggest trying the following:
    1. Set Reg 0x2F[7:4] = 0000'b //Set divider to 2, 4
    2. Determine the appropriate value as directed in Table 18 for Reg 0x60, Reg 0x61, Reg 0x64[7:4] and Reg 0x67[7] based on F1 = 13200 MHz

    Which protocol is your customer using the 6.6 Gbps rate for?

    Thanks,

    Michael

    Hi Michael - san,

    I'm so sorry to be late in answering your reply. I 've almost recovered from the jet lag. 

    The protocol is Aurora 8B/10B. Customer says Aurora 8B/10B is 6.6Gbps.

    Best Regards,
