World’s Fastest Isolated RS-485 Transceiver Demonstration

on Wednesday, 31 May 2017. Posted in Videos

To prove they really are the world’s fastest isolated RS-485 transceivers, NVE’s Chris Olson connected two 40 Mbps evaluation boards with 10 meters of twisted-pair shielded cable.

When the lab results were in, propagation delay measured just 96 ns for two transceivers, and about 33 ns of that was the speed of light through the 10 meter cable. That’s much faster than any competitive parts. Typical pulse skew is only one nanosecond, and the transceivers are also very well-matched—skew between any two devices is only 4 ns.
