SiTime Corporation 1 Hz to 2.5 MHz Oscillators \/ TCXO SiT1579AC-J3-XXE-0146.000000

The SiT1579 is a 1.2 mm² ultra-low power oscillator with a factory-programmable output frequency range of 1 Hz to 2.5 MHz, housed in a 1.5 × 0.8 mm CSP package. It operates from 1.62 V to 3.63 V and draws 6 µA at 100 kHz. Frequency stability is ±50 ppm across temperature, supply voltage, aging, and load, with integrated phase jitter of 2 to 3.5 nsRMS for frequencies above 1 kHz. The device supports operating temperatures of -20°C to +70°C (C grade) and -40°C to +85°C (I grade), and is Pb-free, RoHS, and REACH compliant. No external bypass capacitor is required.
