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,

    There is a trade off for data rate vs. differential input voltage amplitude vs. propagation delay.

    The device performance will be similar to, or better than, competitor parts.

    I do not have access to this information.

    I will need to perform this measurement in the lab.

    However, you would not see 16Mbps at +/-200 mV in a real application.

    So I would like to know why you are asking this question?

    Thanks,

    Richard
