Skyworks Si838xISO-EVB User Manual

UG206: Si838xISO-EVB User's Guide
This user's guide explains the features of the Si838xISO-EVB, which is designed for the
evaluation of the Si838x part family and its recommended bill of materials.
The Si838x product family is a set of eight-channel isolators, rated to 2.5 kVrms, which
utilize LED emulator inputs to drive the isolation channel. Various configurations, includ-
ing the number of high speed (2 Mbps) channels and output types (SPI or Parallel), are
available per the ordering guide in the Si838x data sheet.
The Si838xISO-EVB is populated with an Si8384P and three different input networks,
each representing a recommendation derived from the respective IEC 61131-2 digital
input types at 24 V dc.
The Si838xISO-EVB allows designers to quickly evaluate the Si8384P's functionality
and capabilities by driving either 24V digital logic signals into the test-points labeled
"EXT" or 2V signals into the remaining test-points. For more Si838x information, visit
the Skyworks web site at www.skyworksinc.com. The product data sheet and application
notes should be referenced to facilitate designs.
