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”.
