SiTime Corporation Spread Spectrum Ruggedized Oscillators SiT9045AAB23-33DHA16.000000

The SiT9045 is a programmable EMI reduction oscillator covering 1 to 150 MHz with a frequency accuracy of six decimal places, designed as a drop-in replacement for quartz-based XOs. It supports spread spectrum modulation with center spread from ±0.125% to ±2% and down spread from -0.25% to -4% in 0.125% or 0.25% steps, selectable triangular, Hershey-kiss, or random profiles, and offers eight programmable rise/fall times from 0.25 to 40 ns for additional EMI control. The device operates over an extended temperature range of -55°C to 125°C and meets AEC-Q100 Grade 1 qualification. It features LVCMOS output, low power consumption of 6.6 mA typical at 1.8 V, and provides pin1 functionality for standby, output enable, or spread disable. Package options include QFN formats of 2.0 x 1.6 mm², 2.5 x 2.0 mm², and 3.2 x 2.5 mm². The part is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
