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?
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?
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.
Thank you very much for your reply.
I would like to know about ADM3078 feature, not about RS485 feature.
I know low input level makes big propagation delay at ADI devices.
I would like to see that data.
Thank you for your support.
I know I can't see 16Mbps at +/- 200mV.
I want to see the performance of this device, the limit speed vs input level.
But I see ADI can't show that data.
