SiTime Corporation 1 Hz to 2.5 MHz Oscillators\/TCXO SiT1581AC-J3-33E-0055.000000

The SiT1581 is a factory-programmable, ultra-low power oscillator with a 1 Hz to 2.5 MHz output frequency range, housed in a 1.5 mm × 0.8 mm chip-scale package (CSP) occupying 1.2 mm². It operates from 1.62 V to 3.63 V, depending on ordering code, with a typical supply current of 4.5 µA at 32.768 kHz and 1.8 V. Frequency stability is ±50 ppm over the temperature range of -40°C to 85°C for the "I" grade, with integrated phase jitter of 2 to 3.5 nsRMS and RMS period jitter of 2.5 to 4 nsRMS. The device is hermetically sealed to exceed MIL-STD-883G Method 1014.12, Pb-free, RoHS and REACH compliant, and offers a PFAS-free option. Start-up time ranges from 150 ms to 500 ms depending on frequency. ESD protection meets JESD22 standards up to 2000 V HBM.
