SiTime Corporation Spread Spectrum Ruggedized Oscillators SIT9045AA-13G33SBA100.000000

The SIT9045 is an AEC-Q100 qualified, 1 to 150 MHz EMI reduction oscillator with LVCMOS output, designed for automotive applications. It supports extended operating temperatures from -55°C to 125°C and offers programmable spread spectrum with center spread up to ±2% or down spread to -4% in 0.125% or 0.25% steps, using triangular, Hershey-kiss, or random profiles. Rise and fall times are selectable across eight options from 0.25 to 40 ns. The device provides frequency stability as low as ±25 ppm and consumes 6.6 mA typical at 1.8 V. It is available in industry-standard QFN packages of 2.0 x 1.6 mm², 2.5 x 2.0 mm², or 3.2 x 2.5 mm². Pin 1 supports standby, output enable, or spread disable modes. The oscillator is RoHS, REACH, Pb-free, halogen-free, and antimony-free compliant.
