EVALUATION BOARD USER’S GUIDE
1. Introduction
The Si871x evaluation board allows designers to evaluate Silicon Lab's family of CMOS based LED Emulator Input
isolators. The Si871x 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 Si871x 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 Si871x series offer longer service life and dramatically higher reliability compared to
optocouplers. Ordering options for the family include a push-pull output stage with or without an output enable pin
to select a default output state (Hi-Z, logic-low, or logic-high). The evaluation kit consists of three separately
orderable boards with each board featuring either the DIP8, SOIC8, or SDIP6 package. For more information on
configuring the isolator itself, see the Si871x product data sheet and as well as application note “AN681: Using the
Si87xx Family of Digital Isolators”.
