DS110DF111: Possibility to readout input datarate locked to

Part Number: DS110DF111


Hi,

The DS110DF111 can be configured (=default) to lock to both 1GbE (1.25Gbps) and 10GbE (10.3125Gbps) input signals.

Is it possible to readout the locked VCO Group and/or Divide Ratio used in autodetect in order to determine the input datarate?

    Hi Mark,

    There is a register which can be used to determine which VCO divide ratio is being used.  To access the register use the following code.

    Write Channel Reg 0x0C = 38'h     /* This changes the definition of Register 0x02 

    Read Channel Reg 0x02

    VCO/1 Lock = 00'h

    VCO/2 Lock = 09'h

    VCO/4 Lock = 12'h

    VCO/8 Lock = 1B'h

    To revert back to the normal definition of Channel Register 0x02

    Write Channel Reg 0x0C = 08'h   

    Regards,

    Lee
