What is the storage temperature of LMH1218? It is not specified in the datasheet.

Thanks,

Yong

    Hi Yong,

    It is -65 to 150 Deg C.

    Hi Nasser,


    This question is regarding LMH1218/LMH1219 interface with outside media. We use some old version of SDI interface before like LMH0002SQ (receiver) and LMH0334SQ (driver), which we always add an inductor parallel with a 75-ohm resistor, which is also recommended by datasheet in the typical application. But I could not find inductor/resistor pair in any of the typical application diagram in LMH1218/LMH1219 datasheet. If we use OUT0+/- of LMH1218 and IN0+/- of LMH1219 to drive or receiver from 75-ohm coax, do they need an inductor parallel with a 75-ohm pair in the line? and what will be the value of the inductor if they need it.

    Thanks,

    Yong

    Hi Yong,

    For LMH1218 and LMH1219 there is no need for 75-ohm R and inductor. These two devices meet SMPTE return loss requirements without using these Resistor and Inductor.
