VALUATION BOARD USER’S GUIDE
1. Introduction
The Si87xx evaluation board allows designers to evaluate Silicon Lab's family of CMOS based LED Emulator Input
isolators. The Si87xx isolators are pin-compatible, single-channel, drop-in replacements for popular optocouplers
with data rates up to 15 Mbps. These devices isolate high-speed signals and offer performance, reliability, and
flexibility advantages not available with optocoupler solutions. The Si87xx series is based on Silicon Labs'
proprietary CMOS isolation technology for low-power and high-speed operation and are resistant to the wear-out
effects found in optocouplers that degrade performance with increasing temperature, forward current, and device
age. As a result, the Si87xx series offer longer service life and dramatically higher reliability compared to
optocouplers. Ordering options for the family include open collector output with or without integrated pull-up
resistor or with an output enable pin. The evaluation kit consists of four separately orderable boards with each
board featuring either the DIP8, SOIC8, SDIP6, or LGA8 package. For more information on configuring the isolator
itself, see the Si87xx product data sheet and as well as application note “AN681: Using the Si87xx LED Emulator
Input Family of Isolators”.
