EMI Reduction Clocks
Silicon Labs’ programmable spread spectrum clock generators feature a wide range of programming options allowing
system designers to minimize EMI at the application level. Configurable parameters include spread spectrum percentage/
modulation rate, programmable edge rates, programmable output impedance and programmable skew.
