SiTime Corporation 1 Hz to 2.5 MHz Oscillators \/ TCXO SiT1579AC-J3-18E-0001.000000

The SiT1579 is a 1.2 mm² ultra-low power, programmable MEMS oscillator with an output frequency range of 1 Hz to 2.5 MHz, housed in a 1.5 × 0.8 mm chip-scale package. It operates from 1.62 V to 3.63 V, with a supply current of 6 µA at 100 kHz and an initial frequency stability of ±50 ppm over temperature, including aging, load, and voltage variations. Integrated phase jitter is 3.5 ns RMS for frequencies above 1 kHz, and RMS period jitter is 2.2 to 4.5 ns RMS at 100 kHz. The device supports operating temperatures of −20°C to +70°C and −40°C to +85°C, is Pb-free, RoHS and REACH compliant, and requires no external bypass capacitor.
