Hi, I'm Chris Olson with NVE Corporation. Today we're demonstrating
the world's fastest isolated RS-485 transceivers.
We're using two of our IL3585 evaluation boards,
which you can buy on our Website.
Here's the circuit.
The boards have a 120 ohm termination resistor on each end.
The boards are connected with 10 meters of twisted-pair shielded cable.
The yellow trace is the input; green is the output.
The propagation delay is only 96 nanoseconds for two transceivers,
and about 33 nanoseconds of that the 10 meter cable. is the speed of light through
Now we'll test the fastest competitive parts.
The propagation delay is 140 nanoseconds, or about 45 nanoseconds slower
than with our parts. Here are the IL3585 switching specifications:
Typical propagation delay is 30 nanoseconds,
and we had less than that in our test.
Pulse skew is typically only a nanosecond. The transceivers are also very well-matched--
the typical skew between any two devices is only 4 nanoseconds.
So the lab results are in, and NVE transceivers
outperform the competition.
Our parts are:
Faster;
Have less propagation delay; and are better matched.
The transceivers are available in wide- and narrow-body packages,
and we offer models in unique QSOPs.
No one else has the smaller packages. In addition to being the fastest and smallest,
other NVE advantages are: Virtually unlimited barrier life;
Up to 6 kV isolation; and Extremely low EMI
