1. Introduction
The Si84xxISO evaluation board allows designers to evaluate Silicon Lab's family of CMOS ultra-low-power
isolators. These isolators are CMOS devices employing RF coupler technology to transmit digital information
across an isolation barrier. Very high speed operation at low power levels is achieved. These products are based
on Silicon Laboratories' proprietary RF isolation technology and offer shorter propagation delays, lower power
consumption, improved noise immunity, smaller installed size, and more stable operation with temperature and age
versus opto couplers. The Si841x/2x/3x/4x/5x/6x include up to six unidirectional isolated channels, permitting data
transmission up to 150 Mbps. The Si840x isolator series consists of single-package galvanic isolation solutions for
2
I C, SMBus, and PMBus serial port applications. For more information, refer to the respective family data sheets.
