Local Inputs of the IQMODs and the IQDEMODs

Hello,

My customer has a general question about the IQMODs and the IQDEMODs.

[Q]

Can the local inputs of the IQMODs and the IQDEMODs accept square wave input such as LVPECL, LVDS ?

Best Regards,

    A square wave input like LVPECL or LVDS would not be a typical input signal.  Though not necessarily forbiden, I suspect the operation of the modulator would be impacted by a high harmonic content of a square wave input.  Further, the common mode voltage of the modulator must be maintained which is likely not consistent wiht PECL or LVDS requirements.

    Hello RJH-san,

    Thank you for your fast response.

    A matter of the influence of harmonics, I understood.

    Thank you for your help.
