Spread Spectrum Technology is employed to assist with EMI emission reductions. A Low Jitter version is available as the 9200SSCL . Taped and reeled packaging (1K reels) and loose quantities are available, to suit high and low volume production. Other Spread Spectrum devices are available in 5x3.2 (ACT9300SSC), DIL14 and 9.6x11.4x2.5. A 0.5% total percentage device is available to special order (MOQ 2K).

The modulation carrier frequency is in the KHz range which makes the modulation process transparent to the oscillator frequency. The controlled modulation process can be on all of one side of the nominal frequency (DOWN SPREAD) or equally spread either side of the nominal frequency (CENTRE SPREAD) . If OVER-CLOCKING is a problem to the system then the down spread is preferred.
