Hi, I'm Chris Olson with NVE Corporation.
Today we're demonstrating

3
00:00:15.690 --> 00:00:19.750
the world's fastest isolated RS-485 transceivers.

4
00:00:19.750 --> 00:00:23.950
We're using
two of our IL3585 evaluation boards,

5
00:00:23.960 --> 00:00:26.320
which you can buy on our Website.

6
00:00:26.320 --> 00:00:29.599
Here's the circuit.

7
00:00:29.599 --> 00:00:33.350
The boards have a 120 ohm
termination resistor on each end.

8
00:00:33.350 --> 00:00:37.780
The boards are connected with
10 meters of twisted-pair shielded cable.

9
00:00:37.780 --> 00:00:40.930
The yellow trace is the input; green is the
output.

10
00:00:40.930 --> 00:00:44.559
The propagation delay is only 96 nanoseconds
for two transceivers,

11
00:00:44.559 --> 00:00:49.519
and about 33 nanoseconds of that
the 10 meter cable.
is the speed of light through

12
00:00:49.520 --> 00:00:52.840
Now we'll test the fastest competitive parts.

13
00:00:52.859 --> 00:00:57.300
The propagation delay is 140 nanoseconds,
or about 45 nanoseconds slower

14
00:00:57.300 --> 00:01:03.550
than with our parts.
Here are the IL3585 switching specifications:

15
00:01:03.550 --> 00:01:06.200
Typical propagation delay is 30 nanoseconds,

16
00:01:06.200 --> 00:01:08.340
and we had less than that in our test.

17
00:01:08.340 --> 00:01:12.970
Pulse skew is typically only a nanosecond.
The transceivers are also very well-matched--

18
00:01:12.970 --> 00:01:16.490
the typical skew between
any two devices is only 4 nanoseconds.

19
00:01:16.500 --> 00:01:18.360
So the lab results are in, and
NVE transceivers

20
00:01:18.360 --> 00:01:21.240
outperform the competition.

21
00:01:21.240 --> 00:01:22.630
Our parts are:

22
00:01:22.630 --> 00:01:23.310
Faster;

23
00:01:23.310 --> 00:01:26.610
Have less propagation delay;
and are better matched.

24
00:01:26.610 --> 00:01:29.860
The transceivers are available in
wide- and narrow-body packages,

25
00:01:29.860 --> 00:01:32.280
and we offer models in unique QSOPs.

26
00:01:32.280 --> 00:01:36.480
No one else has the smaller packages.
In addition to being the fastest and smallest,

27
00:01:36.480 --> 00:01:40.040
other NVE advantages are:
Virtually unlimited barrier life;

28
00:01:40.040 --> 00:01:45.640
Up to 6 kV isolation; and
Extremely low EMI
