LMK03033C fail safe

Let me confirm fail safe function of LMK03033C.

I suppose there is no description on LMK03033C datasheet about fail safe.

LMK03033C does not have any fail safe function or circuits, right?

Thanks,

Best Regards,

    Hi Suzuki-San,

    You are correct. LMK03033C does not have a fail safe function.

    Fail Safe definition: According to the TIA/EIA-644 standard, when the receiver inputs are open, not connected to the generator, or if the generator is powered off, the failsafe feature will drive the outputs high. If the receiver inputs are shorted, the outputs will be in failsafe mode (HIGH State). The standard also states that the receiver outputs will also go in to a failsafe if the differential inputs remain within the threshold region for an abnormal period of time
