♪ Beck: Toaster Oven ♪

00:00:08.232 --> 00:00:09.693
We're demonstrating

00:00:09.693 --> 00:00:12.120
NVE's unique high-speed, high-temperature

00:00:12.120 --> 00:00:15.000
isolated RS-485 transceiver.

00:00:15.000 --> 00:00:19.373
With a 125 °C operating temperature
at 40 megabits per second,

00:00:19.373 --> 00:00:24.887
it's the world's fastest
extended-temperature isolated transceiver.

00:00:24.887 --> 00:00:30.000
We devised a nasty torture test to
demonstrate its temperature and speed 

00:00:30.000 --> 00:00:35.694
using a new IL3685TE evaluation board
and a toaster oven.

00:00:36.591 --> 00:00:38.800
The wires feed through the crumb tray.

00:00:38.800 --> 00:00:43.560
There are 120-ohm termination resistors
on both ends of the bus twisted pair, 

00:00:43.560 --> 00:00:46.004
which creates the 60-ohm worst-case loading.

00:00:48.264 --> 00:00:53.326
We followed the quick-start instructions
on the bottom of the evaluation board.

00:00:56.556 --> 00:01:02.280
The transceiver data input is connected to
a 20 megahertz square wave,
which is 40 megabaud.

00:01:02.280 --> 00:01:05.160
The top oscilloscope trace 
is the data input,

00:01:05.160 --> 00:01:08.160
and the bottom traces are the 
differential bus outputs,

00:01:08.160 --> 00:01:10.422
which show the part is working.

00:01:11.049 --> 00:01:13.840
A thermocouple monitors the temperature.

00:01:14.289 --> 00:01:18.040
We set it up for 125 °C, 
which is 257 Fahrenheit.

00:01:18.040 --> 00:01:21.270
We'll see if gets 
hot enough to make toast.

00:01:27.640 --> 00:01:31.960
125 °C is well above 
the 85 °C RS-485 spec.

00:01:31.960 --> 00:01:34.600
It's running at 40 megabaud,
and the bus loading 

00:01:34.600 --> 00:01:46.720
is a worst-case 60-ohms.

00:01:46.720 --> 00:01:51.680
Toaster ovens aren't very precise,
so the temperature hits well over 125 °C, 
and the isolator still works,

00:01:51.680 --> 00:01:54.850
when other isolators would be "toast."

00:01:55.747 --> 00:02:00.000
After about an hour of the torture test,
the isolator is still working...

00:02:06.000 --> 00:02:08.964
...and the toast looks pretty good!

00:02:09.300 --> 00:02:14.600
Isolated transceivers are NVE's 
"bread and butter."

00:02:12.800 --> 00:02:15.700
Our parts are the best things
since "sliced bread"--

00:02:15.700 --> 00:02:18.999
and more heat tolerant than sliced bread.

00:02:18.999 --> 00:02:21.733
NVE has the fastest and smallest isolators, 

00:02:21.733 --> 00:02:26.440
and the highest isolation rating in the industry.

00:02:25.000 --> 00:02:28.400
Other isolators are frauds
when it comes to bauds,

00:02:28.400 --> 00:02:32.700
and if they can't stand the heat,
they should stay out of the kitchenette.

00:02:32.700 --> 00:02:36.169
