Si871x-EVB Si871X LED EMULATOR INPUT ISOLATOR EVALUATION BOARD USERS 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, singlecha- nnel, drop-in replacements for popular optocouplers with data rates up to 15 Mbps. These devices isolate gh-speed hi 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 seriofes fer 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, orogic- l 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. 1.1.
