SiTime Corporation 1 Hz to 2.5 MHz Oscillators\/TCXO SIT1576AI-JE-20E-0660.000000

The SiT1576 is an ultra-small, ultra-low power temperature-compensated crystal oscillator (TCXO) with a frequency range of 1 Hz to 2.5 MHz, designed for battery-powered and space-constrained applications such as health monitors and sensor interfaces. It comes in a 1.5 x 0.8 mm chip-scale packaging (CSP) with a footprint of 1.2 mm² and requires no external bypass capacitor. The device operates from 1.62 V to 3.63 V and draws 6 µA at 100 kHz. It offers ±5 ppm total frequency stability over temperature, with operating temperature ranges of -20°C to 70°C or -40°C to 85°C depending on ordering code. It is RoHS, REACH, and PFAS-free compliant, with integrated LVCMOS output, 2.2 ns RMS period jitter at 100 kHz, and a start-up time of up to 500 ms at 1 Hz. The part is ESD protected to 2000 V HBM and meets MIL-883 for mechanical shock and vibration.
