Hi,
Our customer is confirming whether AM26LV31E/32E devices could be used in data rate 40Mbps, cable length 100ft.
However, I previously got E2E answer in the below URL.

A rule of thumb states that the product of the line length [ft] times the data rate [Mbps] < 2000.
The formula and chart are not hard limits that cannot be exceeded. 40Mbps and 30m(100ft) is possible. However exceeding the suggested limits will result in more noise sensitivity, a short valid bit time window.
How should customer do desk study about noise whether 40Mbps and 100ft is possible ?
In addition, would you give us the explanation of the fundamental reasons that the product of the line length [ft] times the data rate [Mbps] < 2000 ?
Best Regards,
Kato
