SiTime Corporation Spread Spectrum Ruggedized Oscillators SIT9045AA-13-33SBA100.000000

The SIT9045 is a 1 to 150 MHz EMI reduction oscillator with LVCMOS output, designed as a pin-to-pin replacement for quartz-based XOs. It is available in industry-standard QFN packages measuring 2.0 x 1.6 mm², 2.5 x 2.0 mm², or 3.2 x 2.5 mm². The device operates over an extended temperature range of -55°C to 125°C and meets AEC-Q100 Grade 1 qualification. It features programmable spread spectrum modulation with center spread up to ±2% in 0.125% steps and down spread to -4%, along with selectable triangular, Hershey-kiss, or random profiles. Rise and fall times are programmable across eight options from 0.25 to 40 ns. Power consumption is 6.6 mA typical at 1.8 V, and it supports 100% pin-to-pin compatibility with quartz oscillators. The part complies with RoHS, REACH, and is Pb-free, halogen-free, and antimony-free.
