SiT9005 Spread Spectrum Oscillators

SiTime SiT9005 Spread Spectrum Oscillators support output frequencies from 1MHz to 141MHz with six-decimal-place accuracy and offer a flexible spread spectrum configuration. These oscillators address electromagnetic interference (EMI) compliance challenges that often arise late in the design cycle and delay product certification and production. Because emissions testing typically occurs near project completion, failures can trigger troubleshooting, board-level rework, and schedule slips. The SiT9005 mitigates this risk by integrating two configurable EMI reduction techniques, spread spectrum clocking and rise/fall time control, which together reduce emissions by up to 17dB on the carrier frequency and up to 30dB on harmonics.
