The input amplitude dependency of ADM3078E propagation delay

Hi

RS485 receiver should operate by +/- 200mV differential signal.

ADM3078E receiver spec defined the delay time by +/- 1V input.

Could you show us the propagation delay at +/- 200mV input?

How about input amplitude dependency?

Regards

moto

    Hi Moto,

    At what data rate are you operating the ADM3078E ?

    Are you operating the part at less than 16 Mbps ?

    Are you expecting to see a bus differential voltage of +/-200 mV in your application?

    You would need to be using a very long cable >1 km to see a +/- 200 mV bus differential in an application.

    Best Regards,

    Richard
