SiTime Corporation Spread Spectrum Ruggedized Oscillators SIT9045AA-13-XXSAA100.000000

The SiT9045 is an AEC-Q100 qualified, 1 to 150 MHz EMI reduction oscillator with LVCMOS output, designed for automotive and rugged applications. 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. 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, with triangular, Hershey-kiss, or random profiles. It operates over an extended temperature range of -55°C to 125°C with frequency stability as low as ±25 ppm. Power consumption is 6.6 mA typical at 1.8 V, with supply voltage support from 1.62 to 3.63 V. Pin 1 supports standby, output enable, or spread disable. Acceleration sensitivity is 0.1 ppb/g. The part is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
