• ADN2872问题咨询,上电报警

    您好:
    我目前在使用ADN2872这款芯片,但是遇到一些问题,还请您帮忙解答一下。
    下图为所使用原理图:

    使用的输入信号50M(DATAP、DATAN):

    遇到的问题:
    1.芯片上电(VCC=3.3V)后报警(FAIL=3.3V,IMODN=3.3>1.2V报警),造成芯片不能工作;
    2.ERREF不能达到要求电压伏值1.23V,最高只能到1.17V;
    3.芯片资料较少,只有手册,但是其中一些元件参数未给,例如FAIL、IMODN上拉电阻未给出,还请明确。
    以上就是在使用过程中遇到的问题…

    Is it possible to use 2 laser drivers in parallel to have the modulation
    current of 130 mA?  
    Hence it is possible to drive a laser diode which requires a current of 150mA
    with two laser diode controllers in parallel: ADN2872?
