ADN2873 Ibias and Imod

Dear all

I have very simple question about ADN2873.

Could you give me your support?

(Is it OK to write the topic of this device in this place/category? Or couldn't you support this IC?)

Ibias and Imod, the current paramaters are written in the datasheet, can these be regards as the current which flow throught PD and LD?

Best regards,

Parents

    I'm sorry for my late reply everytime and thanks for the lecture and support.

    Current situation, we use MITSUBISHI LD ML720K19S, however it is not recommended by ADI.

    And our current schematic is attached figure, "Differencial" schematic.

    Perhaps you will find that RCL value is not proper soon, and it may be disproper schematic.

    However the "Differencial" schematic achieves high frequency operation; ~2GHz.

    I hope below statement;

    "When use this EVALZ-ADN2871/ADN2873 board to evaluate other differential lasers

    LDs, one optimization work is necessary on the circuitry between the DUT to the LD.

    Please contact ADI sales for the necessary technical support."

    It is written in ADN287x EVB Application note.

    Could you tell me advise for correc design?

    Thanks and best regards,
